That's a beautiful build right there!! I'm curious about your load data and V0 results, are those velocities you're recording at 2810fps the result whilst fire forming the cases from 300PRC to 28SM? I'm curious because I jus received my barrel and am about to spin it up in the coming week to try it out myself... Using ADI AR2217 and AR2225 powders.
 
Yes that was 73g retumbo fire forming the brass I talked to rich and he told me to bump it up too 76 grains and that was shooting at 2942 doing the rest at that charge.
