[QUOTE="0-tolerance, post: 1555784, member: 105966"] Think you Scott for your willingness to share. Another thing I forgot to mention is breaking in and fire forming brass. I do the regular shoot, clean a few times then shoot a few groups then clean. After putting 20 rounds down the barrel, I continue the break in by fire forming my brass doing ladder tests, to about about 100 rounds. This gives me some good data on where to start my ladder. Because it's virgin brass, the speeds are a little erratic but give some good starting point for the ladder test with fire formed and prepped brass. Still saving for an annealer $$$$. Also found that the speeds are erratic with clean barrels. When doing barrel break in, my target has ten points to shoot at for each ladder test. One point per charge so I can watch the shifting points of impact better. It's a lot easier to see this way vs 10 different charges fired at one point. This process works everytime. This process saved me so much headache in load development. I read about this type of ladder testing off an article that probably got it from you.......... so thank you! Did i mention that this process saved me so much headache in load development. Thanks again! [/QUOTE]
