Last night I loaded 3 recipes with WC844, CCI #400 small rifle primers, 62gr M855/ss109 bullets and once fired speer .223 brass. I'm told to use H355 data for my loads, starting with a minimal load and work my way up. My problem is, none of my manuals have data for 62gr bullets. So I searched through the internet and also looked at loads for 63gr bullets. My final decision was to load 24grs, 24.5grs, and 25grs, shoot them and look for signs of pressure. Well, I tested all three loads in 3 different AR's, and managed not to blow up any of them. All loads fired great with no signs of over pressure. Does anybody here have any experience with this powder/bullet combination? I'm still new to reloading, been studying all I can, and so far this forum has impressed the hell out of me(lotsa good folks on it). Am I missing anything?
