Just thinking 6x47 Lapua vs 243 vs 243 AI in terms of barrel life. I'll be shooting the 87 gr VMax's. Just wondering what kind of barrel life I could get from these. I've always been told 243 & especially 243 AI are barrel burners. Looking at the 6x47 Lapua it looks like it would be as well so just trying to figure out the lifespan of the barrel. Thanks.
