  1. As far as the press and dies go, Lee works very well with 10mm. I have them as well as Redding, and can't say that Redding is any better, although the micrometer adjustment on the Redding seater die is a nice thing. I can't say it's worth the money. I have found it very useful to polish Lee or any other dies. I use Flitz and a Dremel, and can definitely tell the difference before and after, even though Lee dies seem to be finished as well as any others. I'm increasingly a Lee fan, they offer a remarkable bargain.
  2. I buy mostly from Wideners, Powder Valley, Precision Delta, and Zero, but I recently got a Class 3 FFL and got the dealer's discount at Graf's. It is well worth doing, particularly if you can put together a $3,500 order to qualify for Volume Freight, and buy powder in 100 pound increments with the case discount (4 x 4# for VihtaVuori, 6 x 4# for Alliant, etc.). Discounts are also available at Midway, and other sources, but I priced very carefully, and for me, Graf's had the best deal. I believe the increase in components prices and decrease in availability we saw in the last Presidential election cycle has already begun, and may be worse this year due to concerns (well-founded or not) about what a second-term Democrat might try with Second Amendment issues, as well as the surge in shooting sports of the past several years. Not to mention that petroleum and copper prices rise at a rate above inflation, and the Chinese are buying copper as fast as it can be mined.
  3. Gentlemen, thanks for the feedback. I mostly have, and use standard Federal primers, I just play Mad Scientist sometimes. Pardon the thread drift, but I recently added a Lee Classic Turret to my loading bench, and am increasingly impressed with Richard Lee's engineering, particularly his primer feed system. Stacking primers (as in the Dillon and Hornady machines) seems more risky than Lee's approach. I'm curious, Objekt, how did your primer detonation happen, a crushed primer, or could you determine the cause?
  4. Thanks. I just emailed the author, Hartmut Broemel, so we will see. I understand that the reason he did not include 700-X was that it was being made in several locations, and the formulation varied so much he did not think it was prudent to release data on it at all. That may be the case here, but if I could get any reasonable data, I could "calibrate" QL so that I could at least predict the increase from a known tested load, which would be nice. Otherwise I'll probably just use up this pound and stick to LongShot and VihtaVuori. It's nice to have options. Is this a great country, or what?
  5. I have tried to contact IMR/Hodgdon every way possible, but they have a Chinese Wall for an email interface. I'm guessing that they make powder more than they do customer support. I think I'll contact the distributor, or the German guy who wrote the program, and see if they will scare up something for 800-X data. As you know, I am a QL-ho, and prefer to use only powders for which I have QL data. In fact, 800-X is the only exception I make for that. It's an interesting, weird powder.
  6. This spreadsheet summarizes my first loading of IMR Hi-Skor 800-X and VihtaVuori N350. Parameters included 180 gr Precision Delta FMJ, 1.26 COL, 45F, G20sf with Bar-Sto barrel, 22# recoil, and GlockWorx race springs. The results are unremarkable. There is no QuickLoad data for 800-X, so I was replicating three values from Hornady 8, and mine were faster than book by 6, 27. and 20 fps. Hornady used a 5" barrel versus my 4.61" barrel, so I'd expect Hornady to be 25 fps faster, but the difference is in the nominal range for QL versus reality. The N350 tracked predicted very closely, as is typical of VV propellants. Because I kept having to adjust POI and move the chrono to stay in light, the groupings were not useful, but the 800-X seemed to tighten up at higher pressures, and the N350 seemed consistently tight. My impression was that if I did not have a RCBS ChargeMaster or suchlike, I'd never fool with 800-X, since LongShot, N350, and several others will do pretty much what 800-X will do, but will also meter well, are not so dirty and flashy, and have a flatter, more predictable pressure/charge mass curve. The added cost and limited availability of VV is worth it to me, since I'm not a commercial loader. No offense to 800-X fans, YMMV.
  7. This eight rung test of 10 mm used one powder, load, bullet, OAL, etc., varying (1) combinations of Lee dies and Redding Competition Pro dies, and (2) magnum and standard primers in these combinations: Lee size, seat, crimp; Standard primers Lee size, seat, crimp; Magnum primers Redding seat, Lee size, FCD; Standard primers Redding seat, Lee size, FCD; Magnum primers Redding size, seat, Lee FCD; Standard primers Redding size, seat, Lee FCD; Magnum primers Redding size, seat, crimp; Standard primers Redding size, seat, crimp; Magnum primers All loads were 13.6 gr Accurate Arms #9 (weighed on a just-calibrated RCBS Chargemaster) under Precision Delta 180 gr FMJ assembled on a Hornady LNL AP with 1.26 COL in virgin Starline brass, load temperature 45F (actually shot at 50-55F) from a stock Glock G20sf except for the Bar-Sto barrel and 20# ISMI recoil springs. Predicted values are from QuickLoad v.3.6. VELOCITY it appears that magnum primers in this load increase velocity about 26 fps: that is, the AA #9 velocity was less than predicted by an average 80 fps with standard primer, and brought closer to predicted with magnum primers at an average delta of 54 fps. STANDARD DEVIATION OF VELOCITY I'm not sure how statistically sound simply averaging summed standard deviations is (I'll ask the statistician, a former Navy Surface to Air Warfare Officer, Monday), but magnum primers reduce SD from 10.8 to 9.2, or 1.6. GROUPS The magnum primers tightened groups a bit. This is pretty subjective (because I am a mediocre shot and shooting through the chrono distracts me), but the groups from magnum primers were definitely slightly better, and if I get a Ransom Rest or a better shooter at a greater distance to the target, I am pretty sure I would verify that magnum wins here. LEE VERSUS REDDING I think this is scant data to make a call, but it is interesting that the lowest single SD (5.9) and the lowest pair (5.9 + 8.9 = 14.8) is with the Redding Competition Pro seating die and the FCD. I really have seen very little COL drift with eather seating die, so I'd hazard a guess that <if> this is a significant difference, the FCD accounts for it. CONCLUSION I will probably try this again with another powder, but I am on the basis of this dataset going to agree with McNett that magnum is the default primer for denser propellants and greater bullet weights in 10mm, and I believe I will continue with the Redding Competition Pro seating die and the FCD until I see a reason to do otherwise.
  8. So yesterday I loaded 50 IMI 125gr Frangibles ($70/1000 shipped from Wideners, planning to stock up) using 1.26" COL, Federal LPP, 9.3gr LongShot weighed on the ChargeMaster; once-fired Starline brass with .4205" crimp; shot on a Glock G20sf with Bar-Sto barrel, 22# ISMI recoil spring, and ZEV Competition Trigger Set. I got several FTF's, apparent light strikes, as the striker seemed to have hit properly (see image at https://sites.google.com/a/sanfordconsultin...t/home/imi-ftf). What is up with image posting on this forum? I am perplexed, and seeking suggestions from you. Possibly relevant observations include: The cases <may> have been a little wet when I loaded them (I had just tumbled them in stainless steel pins in the Thumler's Tumbler), or this load needs a magnum primer (checking against prior LongShot loads for % filled, pressure, etc.), The race springs were suddenly inadequate on even Federal primers (changed the striker spring at range, no help). Have returned gun to stock springs except 20# recoil I had bad primers (will load 25 with another batch of standard Fed and 25 with magnum in bone-dry cases to test 1 and 3), Gun was dirty (unlikely, but detail stripped and FrogLubed all parts last night), Rounds that fired were very loud and had significant felt recoil, but I'm not used to 125gr in 10mm, nor LongShot, really. Georgia Arms 180gr FMJ all fired perfectly. I don't think it's the bullet, because that would likely resulted in Failure to Feed. I will review loading parameters. Any ideas, in case I'm overlooking something? Thanks.
  9. I'm inclined to run a test of 180gr Precision Delta FMJ RN bullets assembling with (a) Redding Competition Pro dies versus Lee, (b) Magnum (Federal Match GM155M) versus standard primers (Federal 150), and © the Lee Factory Crimp Die (FCD) versus the Redding crimp die. So that will be: Lee dies: (1) Standard primers, (2) Magnum primers; Redding sizing and seating dies: (3) Standard primers, FCD, (4) Magnum primers FCD, (5) Standard primers, Redding crimp, (6) Magnum primers, Redding crimp. I gather that McNett uses magnum primers with about every powder, and that general advice is to use magnum primers with slower and denser powders. So my question is this: If you were choosing from Longshot, Blue Dot, Power Pistol, 3N37, 3N38, N340, N105, and AA #9, which would you choose for this test? Which powder best justifies magnum primers, assuming a slightly compressed load (if needed)? I suppose I should change to 200gr bullets, and maybe I will, but 180gr is what's on my bench at the moment. Thanks.
  10. I am not TaosGlock, but I sent you an email.
  11. I've Googled this, and sent an email to Redding, but do any of you know whether other than the micrometer adjustment stem on the Competition Pro, is there any difference between the Redding Competition Pro and the Pro die sets? Are the internals the same? I am particularly interested in 10mm.
  12. Thanks for your kind remarks about this spreadsheet. I originally entered only 180gr data, but today I added all data currently in hand for these grain weights: 135, 150, 155, 165, 170, 180, and 200 (including, due to popular demand, powders I don't plan to use, like Unique) from Hornady 8, Speer 14, VihtaVuori Reloading Manual 4, LoadBook 2004, QuickLoad 3.6, and my load development. I initially entered data from various forums, Lee 2, Hodgdon/IMR/Winchester 2010, Ramshot 4.4, Accurate 2010, and Lyman 49 for the 180 gr bullets I was loading, and will add the non-180gr weights and powders from these other sources as time allows, maybe today. As I mentioned earlier, all disclaimers apply, there may be errors in this data, the data may have different results in your gun or if you make any changes in the conditions, you should start low and work up, loading may be hazardous to your health, etc.
  13. I completed last week's load development. Turns out you can chrono just fine in a light drizzle. The results in the original format (four groups of increasing powder weight for all eight powders) is at https://docs.google.com/a/sanfordconsulting...;hl=en_US#gid=1. I rearranged the data into what I think is a better format at https://docs.google.com/a/sanfordconsulting...hl=en_US#gid=10. The latter format shows all four rungs of a ladder on one sheet, and (1) simulates the way I'd ordinarily shoot a ladder, one powder at a time, so I can feel the effects of increasing weight; (2) facilitates adding graphs for Pressure versus Velocity and Actual versus Predicted Velocity; and (3) will be the format I use going forward. The grouping data is probably marginally useful, because shooting groups at the same time as chronoing is distracting, and I sometimes had to reposition the point of aim to avoid shooting the chrono, etc. I'll shoot groups later for selected rounds without a chrono. However, although a low standard deviation (SD) is not always associated with increased precision at the target, the SD's here give me some clues as to what loads to pursue. VihtaVuori 3N37 seems to be the SD winner, and tracks QuickLoad (QL) very closely, although the N340 was also good. The Power Pistol (PP) load I was fretting about, 9.9 gr, was just fine, and was the third highest in velocity of this bunch, 1,303 fps at 36,252 psi. Going above 9.9 gr does not noticeably increase velocity in PP with this round, according to QL. LongShot ran fastest, 1,324 fps at a comfy 35,829 psi. There's only about 20 fps more available before exceeding 37,500 psi. BlueDot (BD) was second fastest (1,319 fps at a mere 28,514 psi). If you are comfortable with 17% compression and about 38,000 psi, which I am not, I believe BD would run about 1,370 fps with this round's parameters, although I would not recommend this, particularly at colder temperatures, because of BD's pretty clear inverse temperature sensitivity and somewhat odd pressure/velocity characteristics. Speaking of which, I got this email from the Technical Service Manager at Alliant this week: "Blue Dot does up a bit at cold temps. I do not know how this could be put into the QuickLoad system. I will pass your comments on to one of our engineers for their comments.". I hope to get better factors including Ba for BD, but I know of no way for QuickLoad to account for inverse temperature sensitivity, so I will not likely play much with that. I'm likely to stick with VV powders for less flash, less soot, and better metering, and PP when I want to save some money. That's kind of my general strategy anyway. I think 1,270 fps is all I can comfortably get from 3N37 (at 37, 628 psi), but the truth is I don't plan to load everyday 10mm much faster than 1150-1200 fps. So it was a good day at the range. My BIL brought down his AR-15, a jacked up piece with too many mods to mention. It shot sub-MOA like a breeze at 250 yards. Cap'n Tom's was not open, so we ate at the Blue Mist BBQ, which was okay, but it is certainly not Lexington #1, the Finest BBQ in The Universe. South Carolinians, please hold your comments. Charlie was so enamored of my BIL's H&K USP .45 that he hardly shot his own G27. Charlie likes those 100+ year old cartridge designs .... (the writer reloads and dons protective gear while affirming that John Moses Browning was a Genius and Prophet, and that the 1911 is a fine shooting platform, my favorite of the last century).
  14. I have yet to find a way to grant limited editing privileges to unauthenticated users, but because I have gotten numerous requests for that sort of capability, or an Excel version, I made an version editable by anyone with the link, no login required. We'll see if everyone is responsible and returns the sheet to the shape they found it, deletes or changes the data, etc. However, now you can sort the sheet for powder, bullet, source, or any of the columns by highlighting a column and going Data> Sort sheet by column .... Probably the best thing is to make your own copy at Google Docs, and then you can edit your heart out without affecting the sheet for others. You will not, in that case, get the other bullets, powders, weights, and so forth as I add them (real soon now!). I'm not very comfortable with this approach because of concerns with data integrity, and will continue to look for an alternative, at which point I'll take this one down. https://docs.google.com/spreadsheet/ccc?key...NktWWWtPaHQweVE Cheers and safe reloading. If there is data you want added, send me a link or whatever by PM.
