Rem brass is the only brass tested so far,but if I can find some Win. localy I'll try some of it.For right now I'm waiting on the 30 06 barrel to get here so I can use it on Hogs.I'm not real sure what I'm doing with this close tolerance chamber,and I'm not geting any pressure signs at all,so its hard to guess how much more powder this thing will take. Guess I'll have to break out the chrono and use it also.
The 243 barrel is just something to play with until I get the 30 06,and after I get it dialed in I may play with this one again.I've got plenty of varmit caliber rifles,220 Swift,2 204 Rugers, 1 223, 1 17 hmr,and somemore that I can't think of right now.(1 22 250) Digger
