shot my lapua build today for first time. mixed results. last 3 shots looked prettty good. brass looks like it's taking a beating already. round marks on base like there is excessive pressure. only shooting 35.3 grains of reloader 15 with 123 a-max. didn't chrono yet. first 5 shots out of brand new barrel. I heard some people shooting 38 grains??? going to clean barrel and shoot next 5 shots. thinking about toning them down a bit. I'm thinking I should probably take my chrono up for the next 5 shots cause it blows my mind I'd be getting that high of pressure with 35.3 grains. It didn't knock out primers and didn't kick at all but geez not sure what do do next.
