[QUOTE="vancewalker007, post: 2238035, member: 66917"] One thing you can do if you want to do a barrel break-in procedure, ie. shoot and clean type, you can monitor the powder load versus velocity so you have a record to track when your barrel settles into a steady velocity. Some barrels will settle around 100 rounds some will take more. My latest barrel took 254 rounds before the velocity settled in. Usually the velocity will jump up some. So for example maybe 60gr of H1000 with 150gr bullet was giving 2900fps suddenly that same load will give 2945 and will settle around that range. Ladder testing is still valid to try as those results are more related to pressure jump points, it will just be the case that the same pressure will give a little more velocity at some point in the barrel's young life where it settles.
