[QUOTE="ShootnMathews, post: 1165167, member: 59915"] First I'll say Len's post was great. Thanks As for my breakin. Different people have differing beliefs on what the breakin does and how to do it. My personal opinion is that on a factory barrel it takes "X" number of shot to break the barrel in with the number being different with each individual barrel. I do not belief that any different method of break in accomplishes the break in any faster. I only believe that some methods make the process easier. I personally use the break in process to begin load work up. I clean my new barrel first with boretech. Load rounds with increasing powder charges up to slightly over book max and at .015" jump to lands. I'll shoot those at 100 yards making adjustments to zero the scope and inspect each spent brass for pressure signs as they come out. When I reach my rifles max ( see pressure signs). I stop and give the barrel a thorough cleaning with boretech and nylon brush. I'll then back down 2 grains from max and load 3 shot groups every .5 grains up to max. I'll shoot those at 100 and clean barrel between groups. Note that each load starting on a clean barrel you're most likely not going to see super groups as usually some fouling is needed to group well but what I'm doing is breaking the barrel in and trying to narrow down where I will focus my load work.
