I will be receiving my first custom rifle with in a couple of weeks, it's a .338 Edge. I was wanting to begin loading some test rounds for load development. What do most of you do when making loads for the barrel break in period? Should I just load 20 or so rounds at the starting charge weight and just use them for break in and don't shoot for accuracy and precision? Or can you go ahead and load in powder increments for load development at the same time as breaking in the new barrel?
