Default Next hunting rig in the works!

So ever since I got the .277 Wolverine I have been wanting to get another Wildcat in the AR-15 and figured I would make a step up and wondered across the 7mm Valkyrie. It is pretty much a 7mm-08 in an Ar-15 platform. The parent case is a 6.5X47 Lapua and out of a 24" barrel they have 140gr bullets cruising at 2850 (max) and 130s pushing 3000 fps (max). Seems like a lot of power for the Ar-15 and could make out to be a nice light weight hunting AR vs the alternative of toting an AR10. Anyways here are a few pictures of the cartridge. More than likely I will probably go with a 20" barrel still haven't decided yet but the 20" barrel seems like you are not loosing that much velocity compared with the 24"

Wildcat+ AR+ reloading= bad addiction

It sure does seem like that and pretty curious to how it will print on paper then onto some deer and maybe take it along on an elk hunt.

so explain to me how your outrunning a 7mm/08 with less capacity?

Been trying to wrap my head around that myself. Same weight bullet+ LESS case capacity= slower no matter how I try the math. I get around 3000fps with 139gr Interlocks out of my 24 inch barreled AR10 7mm-08 and around 3050 out of my 28 inch barreled pro hunter. Both of those loads are around 102-103% load density without being compressed. It's impossible for me to figure out how you are getting the same speeds with the same bullet weight and 20% LESS case capacity. Even using that super fast leverevolution powder just MAY get you to 2600fps but that's a heavy MAY! I personally think someone is fudging some numbers somewhere.

I've been intrigued by the 7 VAR a few times, might still happen. The gap in power and bullet weight above the 6.8spc, 6x6.8, 6WOA, 6.5Grendel, 243LBC, etc does tempt me. The data I've seen puts the Valkyrie somewhere 100-150fps behind the 7-08 with the same bullet, at least in factory ammo. Hand rolled 7-08's can run away from the Valkyrie.

The disadvantage I've seen so far, besides making brass of course, is the barrel length needed to get the velocity. Much of the data available for the Valkyrie right now looks great - until you realize it's from a 24" or 26" barrel, instead of the 20 or 22" barrels common for 7-08's. In short barrels, it seems to rank about the same as the Grendel or SPC cartridges.

I still think they are fudging the numbers somewhat Mercy. Even with a 24 inch barrel you would be hard pressed to get me to believe you can achieve 7mm-08 speeds from over a 20% drop in case capacity using the same bullet weight. They MAY get relatively close to a lite loaded factory round with theirs being hot rod loads. But if you do a TRUE comparison, both cartridges compared equally in powder fill (both cartridges filled to top performance) and barrel length then there is no physical way possible it can achieve the same speeds or even close for that matter.

The numbers seem an awful lot like a .260Rem, but shorter.

I never said that.... I said "It is pretty much a 7mm-08 in an Ar-15" I was realating this wildcat to something that is a commercial cartridge...

Out of a 24" barrel they are getting 140gr loads going 2750-2850. Hornady factory 139gr American Whitetail line it has it going 2840fps. Shoots a .284 bullet and has about the same ballistics of a 7mm-08 that is why I stated that.... But here is the recommended powders Leverevolution,CFE 223, xbr 8208, H335,Benchmark, AA2520, TAC, AA2230 and Xterminator. And from the Facebook community a lot of people are running velocities close to this...

A 20" barrel will push the 130 close to 2800 fps. To me it just seems like it would be a nice light weight Ar-15 to use for if your hiking etc... Plus I just like wildcats lol
