Yeah, I know this is in the 6mm BR section but I stand the best chance getting advice here I think. After all it is a small cartridge case. I shoot 6.5 Saum, 30-375R for big rifles, 6x47l is the go-to for steel and comps(high performer but poor barrel life/1500 or so), but I just want another nifty cartridge that gets really good barrel life, doesn't use much powder, has low recoil, and gets decent ballistics in the wind. I'm mostly a steel shooter and that's what I will use this for. With my 6x47l I stop shooting early and shoot the least I can because I want to preserve the barrel. It would be nice to save the 6x47 barrel for comps. Plus where I shoot I start at 400Y and go to almost 1200Y as normal. In the back of my head I can't stop thinking about something like 6.5 BR AI. A handy 26" medium weight barrel. 123SMK or 130 hybrid at 2600 - 2700 fps maybe, 4000-5000 barrel life to 3/4moa. Am I wrong thinking the 6mmBR gets in the 2500-3000 rounds barrel life and the improved versions less? I'm not a benchrest shooter but do like to squeeze all the accuracy I can get so that's why I'm considering the 6.5 version. What are your thoughts on this???
