  1. While this is an older post, now going on 4 years old, reloading or historical reloading data is like a cook book, it really never goes out of date. Nice start Greg. This is all without load data. I have a bit of experience with cats, making, designing, shooting, creating reamers, etc. One of the most infuential designers for the little cata was Wes Ugalde of AZ. He created what became known as the TCU line of cartridges, after Thompson Center started chambering their Contender for them, the 223 catted from .17 to 30 cal. His designs of three cartridges are some of the very best cats using the 223 case, the 6mm TCU, 6.5 TCU and the 7mm TCU. Each is very accurate and can be formed with a single pass of a full length sizing die. Fire formed and trimmed they are quite accurate. With the 7 TCU out stripping the rest for popularity in silhouette shooting, due to its versatility in cast or jacketed bullet shooting with various weights of bullets. My last 7TCU XP-100, I held on to, after I retired from competition, was the last gun made by the father at Sinclair. It was previous owned by Frank Howe, the FL State 4 time silhouette 4 gun champion. The 6x47 is the big brother of the 223 cats, based on the 222 Mag. It makes a very fine rifle or single shot handgun chambering. I owned a Sinclair made XP-100 in the 6x47 chambering. A bit too long for the AR-15 with larger bullets. Today the 6mm Mongoose, a newer cat offering by MDWS, can actually be made by using the old 6mm TCU dies. I built one of these 6 Ms which is .050 shorter than the 6x45, with a blown out body, to see how it would work out, just out of curiosity. 18” SS McGowen 1-8 twist bbl in the AR-15. I decided to use Surplus W844 powder and Rem 80g JSP FB bullets to put it to a test. Fire forming, at a mid load, it shot .3” groups right out of the gate. A yote came up out back in he rain, at about 75 yards, and it got tired and had to lay down. I have owned or own several 7.62x39 based cats, from a while ago. Grendel, ARcs etc. Also the 6.8 SPC cats. I created the first subsonic 160 grain fully functional AR. Posted a 3 page document on how it was done on the Grendel forum. I did own the 300 Whisper, the 6.5 JDJ of J. D. Jones of SSK and cartridges Jim Rock of RPM/XL, were both old IHMSA Match Directors. I have owned both of their designed cartridges and barrels when both were living. I have owned Bert Stringfellow BF guns and Richard Mertz MOA guns also. The 30 American was basically a 30 Grendel for the MOA. Today I still have a 6.5 Grendel and 30x39 AR-15, they are both fine cartridges. I prefer Win 7.62x39 brass for the Grendel with 120 SMKs and the 30x39 with 150 SP FB bullets. The advent of the 308x1 1/2 gave rise to the BR line of cartridges that immediately turned to the wildcatting of a cat, as happens in this world. Then the standardization of the BR cats such as the 22 BR, 6 BR and 7 BR when Remington started offering the BRs as XP and Rifle chamberings. I have owned several including the 6 BR, 6.5 BR and 7 BR. My favorite of this cartridge base cat is the 6.5 BR which is very accurate with the 120g SMK. I built an XP-100 in 6.5 BR as my 1/2 size competition gun. I built a 308 caliber revolver based on the DW Super Mag frame. The barrel was a Douglas 1-10 twist air gauge premium 10” barrel turned and threaded for the DW frame and shroud with a 3” long nut wrench. The cylinder was a 445 Scored Super Mag cylinder, reamed for six .308 chamber inserts, turned to sime OD as the reamed ID, then put in a freezer and pressed into the reamed holes, then chambered using a 4 jaw chuck. The cartridge was a straight wall case based on the 25-20 case necked to 30 using cut down 25-20 dies, eliminated the neck and 30-20 seater dies. A revolver chamber reamer of my design was made by Clymer, it cut the chamber and rifling out in front of the chamber. It would do 1,600 fps with a 150g FB bullet and shoot .5 inches at 100. But it actually shined with cast rifle bullets of 165, 180 and 200 grains. Bob, the new owner of DW liked the idea but by the time my testing proved out, CZ had bought DW and we all moved on. I simply proved one could take advantage of the SD and BC of .308 rifle bullets in a revolver. The 25-20 straight case has the same diameter and taper as the 30 Carbine, with a bit more capacity and a rim. The full length 308 cartridge case allows for all manner of cats, with outstanding performance. Some of these shine in the AR, bolt rifle and single shot hunting handgun category. The 6mm or 243 is formidable with a 1-8 or 9 twist bbl. The 6.5x08 is so good, Remington just changed the shoulder angle by 2% and called it the 260. The 7x08 is a great cartridge and the 358 Win is an excellent woods deer cartridge. These were all wild cats at one time. I built a 6.5x08 XP-100 14”, it was the only gun I ever got asked not bring back to a range. It had a vicious muzzle blast at 3,000 fps, with 120s and H-414, felt like someone stealing the air out of your lungs from the concussion when it was shot off the ground. It was my long range silhouette gun, built for 500 yard handgun competition. In my M-700 custom Lothar Walther 1-8 twist 26” bbl gun it does 3,215fps at .1 inches at 100 and .75 inch at 500. Note this is the 6.5x08 not the 260 and is so, very much of a purpose. Some today are making short 308 base sized cases for use in the AR-15 magazines with oversized bolts. Makes an interesting project. My favorite 6mm cat to make, just for my own sheer aggravation, was the 240 Laser, designed by John Bass, ballistics engineer on the GAU-8 ammunition project (30mm of the A-10 Warthog) Basically it is a 280 necked to 6mm with the shoulder moved forward to create a body .100 longer than the 240 Gibbs, with a 40 degrees shoulder and the case body blown out to a 243 cartridge taper from the shoulder back, to the 243 case body length, then straight from that point to the 240’s base. The cases are fire formed using a false shoulder with a single heavy dose of 870 powder. It will do 3,800 fps with 115g VLDs and tied the then world record 5 shot group at 1,000 yards. The first production run VLDs were sent to John for testing in this very rifle. John built the pre 64 Win M-70 with the 1-7 twist Lilja 30” bbl gun, I bought from him. It is about the largest capacity standard base diameter 6mm cartridge ever built. Having 500 yards to shoot this rifle was very much like shooting a 50 BMG rifle at 500, not far enough. John’s favorite adventure is to create a new cartridge using an existing die set and existing chamber reamers. The big 240 Laser case can be reloaded using 243 dies set to neck size and to seat, for example. I say “the big” because there is a 240 Baby Laser, made by running a 243 reamer into a .243 barrel until a 6mm Remington Go Gauge allowing the bolt to close, it fire forms a longer 6mm Rem case to a 243 Win diameter with minimum taper. Somewhat similar to the 6mm AI but more capacity. It is extremely accurate with a 1-8 match, premium quality barrel.
  2. Might as well post the “pretty.” This is the English walnut stocked 222R Martini Cadet I built. My blank, turned by me, barrel made by me, etc. A very nice piece of wood on a neat little rifle, made for an Aussie cartridge designed for the Cadet, easy to reload, that really shoots well.
  3. Had several older single shot smiths tell me that I could not build a Cadet 357 Super Mag, the case would not not “make the curve” into the chamber. So being the nothing is impossible kind of person, I studied the problem, did some scale drawings, etc. Then I made a chamber from a rusted out and reamed Cadet barrel. Took a 18” short 1-14 twist 358 barrel blank, turned it down, allowed a 6” straight chamer area installed two 541 scope bases, threaded it and hand cut the extractor slot and slopes, made an extractor, firing pin bushing, chambered the barrel, made a pull bolt butt stock from a blank, formed the lever, made a for-end, the for-end escutcheons from two 357 SM cartridge bases using the primer pockets. Did a trigger job. Polished the metal and blued it. 100% glass beded and separated the fore-end from the action. It shoots .5 inch groups at 100 with 180s and 200s. This is the Martini Cadet 357 SM that could not be made. I made this rifle near 30 years ago now. It kills deer with authority. Makes a nice fun gun for the grand kids that want something to shoot that makes big holes without a mean recoil.
  4. The only center fire cartridge I did not reload for was my little pocket pistol in 380. I never shot it much but carried it every day. So I decided to buy another $12 box of Corbon ammo and I found one, 20 round box for $50. Yeah, right! Being a nice, but a do not try to pizz on me and say it is raining, sort, I bought 1,000 bullets, 500 pieces of once fired brass, a carbide sizing die, a taper crimp die and after using pieces from 3 die sets and a 223 shell plate on my Dillon, loaded one 380 95g made from a 100g FMJ on my lathe. Have a bit of testing to do, past the OAL setting, but it will take a lot of powder, 2.9g of Bullseye and 4.5g of Unique is a max load, so I could not wear out a pound (7,000g) of powder making 1,000 rounds, awh shucks I have had several folks want to trade me already for 380 ammo, interesting, isn’t it? A 1/2” center drill run in .100” will change a 100g to 95g and make a fair sized dimple. Not to bad for a 10’ range little backup/defense pocket gun. Especially if you can do around 1,050 fps with Unique and be under a max load. That is approximately the advertised Corbon load, with a 90g JHP.
  5. My interest in the NFL is just in passing, for sure. However when the Jaguars drafted Trevor Lawrence #1 and then turned around and drafted Travis Etienne, well that was a good lick in anyones day, if they can actually play in the league. So many have not lived up to the hype, prior to the NFL. I have no intention to watch, but giving the Devi his due, so to speak.
  6. Necessity is the mother of invention and today you might do many things you would not do otherwise. If you want to pull bullets and reload factory it is just a little complicated. You follow the same steps as a commercial demil contractor. You pull the bullet with a collet bullet pullet, clamp it pretty hard, then pull the bullet in the press, pour the powder from the case out in a weigh pan, weigh the charge, pour the powder into an empty and clean container if you want to reuse it. Remove the decapping pin from the FL sizing die, lube the case, and full length resize, put the powder charge you wish to use, back into the resized case with a powder throw set to your charge weight, seat the bullet to your desired OAL. If you want to recrimp, do so now, otherwise, go shoot.
  7. This Ruger CC 1911 slide was done on the surface grinder I had an opportunity to buy, but passed on. I just did not have the frequency of use to qualify the complication of 3 phase VS single, all the add on pieces, the table and the space for its use. If you have the frequency of need/use, it is hard to beat as a shop tool for sure.
  8. I had some originals that I gave to my son then my son in-law, ending with me getting stuck with the noes that pop open, which I threw away. I really could use a good set on the farm, a true 100 and 1 use tool when you are working in the field, away from the shop building. Funny thing is stuff rarely breaks where it is convenient, on a farm.
  9. There is a never ending bread crum trail of tools and jigs for mills, including tools to make tools and jigs to make more jigs. I had the unfortunate experience of having a smith drill and tap a receiver for me with a vise off square. The 4th hole was 1/8 hole off center from the #1 hole with the rest in a straight line, but at an angle to the center lne. When I got my Forrester drill & tap jig (another jig), I straightened that out myself so I could use the receiver. However it required more drill bits, more taps, more collets, more thread cutters, more cutter handles and more screw blanks..... Yeah, more and more stuff....
  10. “I have a 14.7in that I cut off the pinned and welded A2 cage, I'm going to pin and weld a DeadAir flash hider.” I think you mis-read the OP. Without a threaded on extension, bored on the interior and the exterior is threaded for the FH He will never get the GB off unless the extension is a smaller OD than the trunnion, you could unscrew the FH and or suppressor but not the extension if it is blind pinned. It does not need to be pinned and welded only blind pinned.
  11. You are aware that by ATF rules, you can legally change the short barrel length to 16” or more with an extension, only if that extension is welded on to the barrel or “blind pinned” on to the short barrel, correct? If you want to change gas blocks after the short barrel non removable extension is added, you must make sure the extension’s OD is smaller in diameter than the OD of the gas block trunnion on the barrel, to get the gas block off and put another gas block on the barrel. A registered suppressor has nothing what so ever to do with the gun it is on, regards registration of the gun itself. So a short barrel rifle, SBR, is its very own problem regards ATF registration. With a rifle, the barrel length must be 16” or more. Once manufactured as a rifle, always a rifle. Even the Thompson Center guns can not mix a pistol barrel with a carbine kit. A pistol, manufactured as a pistol, can have any length barrel, but no butt stock. You can not make a rifle into a pistol without ATF registration. Regards the adjustable gas block, if you are shooting factory 5.56 ammo there is little need for an adjustable block as the AR-15 is designed for that cartridge and the NATO specs are set to function a Mil Spec AR properly. Originally designed for the use of the 55gr at 3,250 fps. However when you start reloading, using different bullet weights and different powders, the adjustable block does come in handy to change a high pressure, so called over gassed, situation at the gas port.Timing, timing, timing is about 90% of the setup for the AR. Just make sure you get a block that is adjustable from outside the forend. With a suppressor, a super sonic bullet pretty much gets you a very expensive flash hider. The bullet crack is about as loud as the muzzle blast, the action clatter, plus the impact sound can not be mitigated much at all. If you are running factory 5.56 with a suppressor, do not expect quiet, unless you are watching a movie. Your sonic speed threshold in Live Oak should be somewhat similar to mine, about 1,100 fps, so you can load to a 20 to 30 fps under the actual fps with a good standard deviation and extreme spread that keeps you below your fps limit with your can. I increase the energy by increasing the bullet weight, keeping below 1,100 fps. I shoot 220gr in my 300BO, 230s in my 358 MGP and 160s in my 6.5G. I have adjustable blocks on them because I shoot them sub and super with and then without a can, using different powders and bullet weights. I do not worry with the clatter of the AR action. You could use the adjustable block to turn the gas completely off and use the AR as a single shot clip fed rifle. Be very careful with multiple ARs and the short barrel(s) in the mix. The suppressor can be used with any gun, because it is a registered item all by itself. But you can not mix and match different AR lowers, some registered and some not registered, with a short barrel upper. The AR itself has but one serial number and that # must match your paperwork on a SBR filing.. You must watch the ATF rules because their proclamations and interpretations take the form of law and they change things you know as being OK to not being OK, or vise-versa, now and then. I hope this helps you.
  12. My spell check running amuck again, I am afraid. My family came to Charlestown in 1754 by ship. Is one of the founding families of The Dutch Fork.
  13. You have a penchant for comparing pineapples to oranges and somehow imagining you have made a proper comparison. What is the source of that ability, your intellect? I spoke to my 3 year old granddaughter on Sunday, she made more and better sense but she is a gifted child.
  14. The history books report that the war began on 4-12-61 when the Confederate forces fired on Sumpter, but.....actually it began 8 days before when Lincoln ordered Sumpter reinforced by a fleet of ships. When you win you write the history to suit, your narrative. The two southern states with forts in their major harbors occupied by Union troops had ordered those troops to be removed, Ft Pickens of Pensacola, FL and Ft Sumter of Charleston, SC. Lincoln was told in writing, that any attempt to reinforce the forts would mean war. Lincoln was busy trying to keep, by negotiation, VA in the union and assured the Governors of SC and FL that the forts would not be reinforced. Then on April 4, 1861 he secretly ordered, in writing, that Sumpter be reinforced with food, ammunition and 200 troops by a fleet. The Confederate spies observed the fleet leave and so advised the government in Montgomery (original Confederate Capital in AL). When that fleet was spotted off Charleston harbor on 4-12-61 the shore batteries were ordered to and did open fire on Sumpter. On the 13th Sumpter surrendered. Lincoln, then called for 75,000 troops and VA with 4 more states left the Union. The flames of war had been ignited. A terrible war over money, not slaves. Most wars are actually about money, who has it, who keeps it and how much goods cost. Slavery was just camouflage for high tariffs and the interest of the bankers, manufacturers and industrialists of the north. Those industrialists really cased about slaves, like the ones from China, Poland, Ireland, etc. Over the decades, after the war, many have attempted to color leaving the Union as illegal. Any state could join or leave at will, by the Constitution, until congress, well after the war, made it illegal to leave the union. Much like the Hotel California, “you can check in, but you may never leave.“ Just to make it clear. The South could never have won a protracted war, economically or industrially, plus it simply did not have the young male population to support a long war. The basic math of warfare does not and did not work for a southern victory. Battles, yes but not a war.
  15. That is an interesting late model PT, about 12 ft shorter and much heavier armed than the early PTs with a forward mounted 37mm auto cannon and a 40mm Bofars rear gun. Seems like an interesting mod due to the loss of PTs from aircraft attack from their stern. There is a book about PTs in the Pacific, seems like if I recall correctly it is Night Patrol and it lists all of the known PTs and their fate. An awful lot were sunk by aircraft with no message or survivors. 3,000 gal of aviation gas, wood hull and tracers are a tough combination. There loss comes from reports from coast watchers and JIN ship logs after the war of fires or debris on the water at or near the time they disappeared.
