I've never seen group size change so much with such a small change in seating depth..


I had about 12rds left from each charge weight I put together for load development that were 0.020 off and seated 6 of each to 0.030 off and another 6 of each to 0.050 off. I just wanted to try once more before giving up on the 53gr vmax. I went from 1-1.75in groups from the ones 0.020 off to 0.35-0.65in groups from the ones 0.030 off.. just 0.010 difference... when I'm not on my phone I'll try to figure out how to post a photo
