I am sure this question has been asked a lot, which 243/6mm do you guys prefer. I plan on shooting 55 70 and 80 grain bullets so i will get a short throated reamer. Never intend on shooting 100s but maybe i would in the future. I want to build this gun for coyotes and deer in the 8lb range. I plan to have my wife shoot it (make her think its for her) so it cant recoil a whole lot. I have been looking at, tell me if i missed a good one, 6 ppc 6br 243 win 243 improved 6mm rem, 6mm improved 6-284 243wssm and 240 weatherby. The ppc and br are the most accurate i know, but i'd like bigger. I want something cheap to shoot that brass is easy to come by so that kills the weatherby. I read some really bad reviews on the wssm. I dont want to lose an inch of barrel to a rechamber every 500 rounds. That leaves the 243 win, 243 improved, 6mm, 6 mm improved and 6-284. They say the 6-284 doesnt shine until you get big bullets, i dont plan to shoot big bullets so how would it do with small bullets? I am wanting to shoot the 55 at 4-4200 if i can. I dont mind sizing the 284 brass but i'd PREFER to not have to fire form unless there is a big gain. What do you guys think? Also what twist would you go with? Would a 12 stabilize the 80s or should i go 10?
