Been on a hot streak w aa2015 lately, and wanted to try it in my 444. Found a few loads listed online, including bear tooth bullets extensive write up. They list 52g with a LFN, I'm working with the Lee 310g. Above 49g mine are compressed. I loaded at 49, 49.5, 50, 50.5, 51. I'm sure I'm seating deeper then they were with their LFN. Any concerns about compressing aa2015 that much? Or just work up and see.

Accurate powder data online, shows all their max loads are compressed with aa2015.
They show a hornady 265 grain bullet with a 52 grain powder load, so for the 310 bullet, I would start at less than the 49 grain start load and work up.
