[QUOTE="Monterey21, post: 1960258, member: 105626"] I did a ladder after the first few rounds With 4831SC. There was a 4 grain spread with .3 intervals and there were two spots that the velocity was flat. The test was at .025 off. The whole thing was about 1.5” @ 100yds. I did not do the ladder test at different seating depths. I do know the further off the lands the slower the velocity. But I really didn’t notice the cold bore difference while doing the ladder. I never run the barrel real hot. I always fire two then wait 5 minutes between shots. I’m going to keep on until I get 60 or so down the pipe. The velocity increase from shot one thru four can be 35 to 50 FPS. But the point of impact change on the first two shots is what’s killing me. I need to work on me as well. Thanks for all the input.
