    So, Who Is At The Bench Today?

    The American 30 doesn't need fire forming!!!!!!!!! It was always the intent to run through a size die and trim to length. It doesn't matter whether yours was one of the first made or the one of the last ones made, if you have to move the shoulder by firing it's not right and it's not an American 30. Another problem you will find in this chamber is overall length. There is an additional .070 in front of the case mouth. Also another little problem is excessive free bore. It could get by with a lot less. The list is endless as to what caused all the problems with the American 30. Just to name a few , wrong head space gauge, wrong reamer, a total redesign by someone who couldn't tie their own shoes, etc. If you choose to go through all the headache to fire form brass and use up bullets for less than 50 feet per second that's your call, but don't believe what ever is lasered on the barrel. You have a 30 caliber wildcat that fits in an AR. I can say this with certainty because I designed the American 30 reamer. It is the same reamer we used to make pressure test barrels and work up loads. We never fire formed a case in over 3000 rounds that were fired in testing.

    Columbia River Arms/BHW Barrel Sale .308

    Are you really sure you want to go with a 1 in 8 twist? There are lots of options out there that would be a better match. In an 8 twist, 5.56 service rifle loads will run side by side with the Valkerie. The 22 Nosler will out run it by a couple of hundred feet per second. And the 22X6.8 will out run them all. Remember the Valkerie is only .7 bigger in case capacity than a 5.56 and runs at 55.000 PSI. The 5.56 runs at 63.000 PSI. Quite a difference for less than 1 grain of capacity.

    Loading the 6X6.8

    Tinkered is an understatement. ****ed it up is more along the line of what I would call it. BHW tried to design their own reamer and failed miserably. BHW needs to stick with what they know. Reamer design isn't on that list.

    school me on Chronographs

    I had the MagnetoSpeed. It worked fine, but the problem I had was point of impact shifting. I like to tune and shoot for groups at the same time. When using the Magnetospeed, I would have to sight my rifle in after I was finished. I went to the LabRadar and couldn't be happier. I do still us my CED M2 on occasion when I'm shooting my .17's or 20's going over 4000 FPS

    6.5 grendel barrel

    I agree 100%. If you go custom you can get it either way. IMHO the way to go is, 6.5 Grendel reamer run in an extra .010 and use a .125 deep bolt. This would be the best of both worlds.

    HORNADY 6X6.8 ONE STEP DIE INTEREST

    2000 pounds of shot? That's only a years supply for just myself. Lol I would like to get in on a truck load deal though.
  7. I just checked the date on my reamer drawing. I designed the 22X6.8 in Feb. 2013. The reamer was ordered March of 2013. We have been shooting this for a little over 4 years. Federal must not be connected to the internet. A simple Google search of the 22X6.8 will get you information and load data for this cartridge. I would be willing to bet you could even get some load data with pressure numbers. I believe I pressure tested this in May of 2013. I would have gone with Grendel case on this one. In my opinion it is better suited for the style of bullets they are offering. Sticking a 90 grain bullet in a necked down 6.8 case is going to use a bunch of case for no reason.

    6x6.8

    I would go with an 18" Light profile. Another little thing I would do is, thread your barrel and run a thread protector. I wished I had gone this route when I started ordering barrels years ago. Go with the 1 in 10 twist. Any of the bullets that will fit at magazine length will stabilize with a 10 twist. There is no reason for the 9 twist in a 6X6.8. The only reason Black Hole even made a 9 was because their 6X45 wouldn't stabilize the Nosler 100 grain Ballistic Tip. The 6X6.8 WILL stabilize the 100 grain B.T. with a 10 twist.

    45 Raptor?

    So let me get this straight. You are loading a 460 S&W, AKA "V Raptor" using the minimum suggested loads and calling that your maximum load? You have to get to the higher pressures before the Raptor out preforms the Bushmaster. If someone is telling you the Raptor will out preform the Bushmaster at those levels, you better ask more questions. The next thing they'll want to sell you is some Beach property in Az. The 450 Bushmaster out runs it by a considerable margin. It has ready available brass. The 450 wasn't stolen like the V Raptor was. There is a considerable amount of data out there for the barrel length it was intended for. Factory loaded ammunition is available for the 450. I don't see that happening for the Raptor. Now I want to throw this out there. I'm not any kind of expert on this but, I own 2 450 bushmasters a 16" and a 20" on an AR15 platform. I own 1 20" 450 AR10 upper for a DPMS platform. I also own a 20" Savage model 10. I also have the pressure testing equipment to make sure I get myself into any trouble. At the end of the day there is only 2 grains of water capacity difference between the 2 cases. That's not enough to make any difference with a bore this size. It all comes down to being able to out do the other guy. But what are the consequences? That's for you to decide.

    6.5 Grendel Type I and Type II

    I would go with a 1 in 8 twist. The current trend is higher and higher B.C's If the bullet weight stays the same, the only way to accomplish this is with length. The only way to stabilize these long for caliber bullets is a faster twist rate. SAA is a retail vender. They have no ties to Black Hole other than selling SOME of their barrels. If you notice SAA only sells 3 chamberings. Black Hole makes upward of 20 different SAMMI and wildcat chambered barrels.

    6.5 Grendel Type I and Type II

    In my opinion, this isn't all that great of a deal. You do realize the barrels are 1 in 9 twist? That is a deal breaker right there for me. For the money saved, I would go with a new barrel made to my specs.

    69's or 77's

    There is no way you will ever even come close to 2900 FPS with a 130 grain bullet shot from a Grendel case. Even with a 26" barrel you'll be lucky to get 2700 and that would most likely destroy the brass with the first firing. The 243 LBC will do 3000 FPS with a 24" barrel and a 95 SMK. Doing the math as you said, the 95 gets to 1000 faster with less drop, less drift and has more energy. What's not to like?

    Hey R Johnson

    Thank you all for the birthday wishes. Damn I'm getting old.

    Remington 700 in 6.5 Creedmore

    I would also consider buying the fixture to alien the recoil lug. Some try and use witness marks on the lug and receiver. This method is an exercise in patience. Another option would be to have your gunsmith pin the receiver and drill the recoil lug. Either way you go, replace the OEM recoil lug with an aftermarket .250 lug. You will thank me later.
