What's the most effective way of breaking in a barrel and developing a pet load ? Received my custom made .308 Broke in the barrel using this method:Clean ,shoot,foam bore 24hrs,clean ,shoot. x5. Would anybody recommend more barrel break-in ? Perhaps shoot 2 and clean (without foam bore) for another 10-15 rounds ! I will be using .308 Berger 175g VLD over Varget,210M primers and Laupa brass. I received load info. from Berger,they recommend start load at 37.5g and MAX load of 42.0g. But looking on the internet most users use 44g-45g with best results ! Am I doing the correct thing by starting at 37.5,38.5,39.5,40.5,41.5,42.5,43,43.5,44,44.5,45 and firing 2 rounds of each load at 100 yards ? (obviously looking for pressure signs). Cheers.
