I finally got my 7mm Valkyrie AR built. Its designed to get 7mm08 or near 7mm08 factory performance from an AR15. I just got it all together this week and had one trip to the range to get my hunting load for my Mule Deer trip in 8 days to the Sierras so instead of working up from scratch i sort of cheated and used a pet load of the cartridge designer to get sighted in and it worked for me so i stopped there and didn't try anything else i have loaded up. I'll play around with other loads after the season. The pet load was a 140gr Nosler BT with 38.4gr of Leverevolution powder and gave me a MV of about 2720fps. I chronied 3 shots at 2736, 2711, 2717 from a 22in 1/8 twist barrel. I didn't form the brass i just bought it preformed from the cat developer. The rifle worked like a champ cycled perfect, ejected each round and the bolt stayed locked back on the last round fired.

I had 3 mags with 3 rounds a piece 2 shots to get in the square the single shot in the square was walking it in then two groups from two strings.
That's a lot of powder, a lot of mass and a lot of velocity! What case is it formed from?
Its formed from 6.5X47 Lapua and has around 42-43gr of total H2O capacity. A 6.8PRI mag holds 7 rounds and i'm told a 30AR mage will load 10 but have not yet tried it. The designer has a pressure trace system so i was pretty confident is just using his pet load although thats unwise as a general rule for reloading.
Seems like a lot of trouble to go through for limited return. I don't really get the purpose of this. The AR platform has it's uses(I have a couple myself) but this is not really one of them. If you want this power in that form why not get a AR10? For hunting you can get a 7mm/08 bolt-action deer rifle that would hold 10 rounds and be a lot lighter and hold up to the dirt etc from hunting much better. You would also not be pushing the pressure limits and having to get custom ammo, etc. That being said it takes all kinds if this is your thing have fun.

I'm not sure what "trouble" you are talking about. Building a 7mm VAR is not harder than building any AR-15 its the same parts except different barrel and bolt which is different for all the various caliber/cartridges available in the AR15 nothing is different or special about building a 7mmVAR. As far as loading/reloading its just a set of dies like any cartridge the brass can be purchased from the guy that designed the cartridge which is what I did. In other words nothing different. As far as the AR-15 not being used for hunting I guess you share that opinion with Obama, Nancy Pelosi, Diane Feinstein and the rest of the commie left gun grabber fascists. Americans have been hunting with auto loader rifles since the early 1900's.
Hunting with auto loading rifles is a deep part of the American Hunting tradition as is using the same style rifles to hunt that we used in war. That tradition goes back to the very revolution that formed are country. As far as a bolt being a lot lighter this gun scoped is 9lbs about what my dads wood stock 30-06 weighted scoped.
This cat uses a 800 Series beefy bolt from ARP that handles the 308 case head on the 6.5X47 Lapua brass. What do you get for performance from the 7mm Grendel for a 140gr?

yep...still have a few from when H and Co were CO based. used them on 6.5 and 30 BRX and 375BR uppers. hadnt run bullets that heavy yet , mostly Speer TNTs .
I built a few for guys to do subsonic work with , 180 Bergers at 1050 fps , quiet as a mouse through a 30cal can.

Interesting. Which zone did you draw? I have thought of a 6.8 for my wife to hunt with. Post up results if you score.

Fight fire, save lives, laugh in the face of danger.

I'll be in X10 down in Monache. I'm missing opening day due to a friends funeral but heading up after that.

tell be about that 30BRX what performance do you get from a 150gr?
if I remember correctly the 150's were breaking 2700 and being nowhere close to "hot" ..the 6.5 went well into 3300 with Speer TNTs also without a lot of pressure. Its been so long and so many projects ago.
thus far Ive done the Grendel case on .204,224,6mm,7mm,30,338 and 375 calibers.
the BR brass had gotten so scarce and pricey in the obama gun rush .
