Re: looking at getting a 30-378
I owned the rifle you are talking about. I only used 200, 210, 220 and 240 grain The cases were like $55 bucks for just 20 of them with tax. and hot loaded they only lasted 2-3 reloads before the primer was loose. I only shot big game at longer yards along with people I loned it to. I bench rest shot it to 600 about wide spread of about 11.6 inches. It might be me or the gun. But I don't believe in varmit speed for hunting. Dead is dead. I don't do the classic heart lung shot. I go for head or neck. On loan for a Utah elk hunt a 220 went right through a 1/4ing chest shot at 310 yards. and never moved from the spot
When the barrel went before 400 rounds I considered rebarreling to a better 338/378 with a 28-30 inch B. So I just sold it and 200 some cases with all the reloading dies
.270 Ackley improved 29 inch 1.250 dia. target barrel 7mm STW 28 inch 1.250 target barrel. I also love my .458 mag for varmints and the biggest game in the world.
