Thanks for all the replys, I loaded 2 rounds for each weight and both rounds were similar in velocity. I did use a Lee FCD crimp. I'm just now getting into loading for my big borrow guns so I've never had to roll crimp before. I think I'll stay in my flat spot I found around 1750 fps and try again with a roll crimp working up to the same load if you guys don't think it's something I need to worry about. When ever I see something out of the ordinary I usually stop and start over. This is the second load I've tried with this gun, had to scrape the first one
