So, I have purchased my first "brand new rifle", my others have been hand me downs from relatives. I shoot them a lot but recently purchased the following: Savage FCP HS precision 338 lapua Lapua brass Nightforce rings and 5.5-22x50 scope The rifle has been bedded with a Karsten cheek piece attached. 300 grain Bergers H-1000 powder CCI mag primers My question is what general process to many of you go through during the first range sessions of a rifle such as this. For instance, would you load up some random load (say 89 gr. powder with bullets seated to max magazine length) for the initial "break in period". After what amount of bullets down range should I begin to actually ladder test from 88-92 grains? Is max magazine length considered a good place to start with my COAL? To answer my question simply, what would be the steps many of you would take during the beginning few sessions at the range. Seeing how I spend a penny on it, I am concerned about setting up everything correctly the first time. Thanks!
