Does anyone have any experience or Quick Load data for this powder. It falls between RL15 and RL17 on the Alliant burn rate chart. They list from 51.5g to 53g for 150g bullets. This seems like a lot of powder for a .308? I think 46g - 47g is the normal Varget or IMR4320 load. Will 53g even fit in a .308 case...especially a Lapua? (the Alliant data is for Federal cases)
