A friend of mine has a massive amount of 224 valkyrie ammo that he isn’t going to use anymore so I’m looking to put together a 224 valkyrie. He has a bunch of 60gr vmax, 75gr fmj, and 80.5gr Berger federal ammo. What barrels have been proven performers? Not very many options that I can find. What I have found so far is bison armory for a quick solution and craddock or x-caliber for a custom but I’m not sure if I’m patient enough for the long lead times. Planning on a 17 designs folding lower with an aero enhanced upper. I would like to do a 20” but not sure what gas length will be the best.
