500 AutoMax Starline brass 18" barrel AR10, 700gr Hardcast gas check Matt's Bullet, CFE BLK and Lil Gun unless a faster powder might be better like AA#2 or maybe #7. Load Data I have for Lil gun is 27.0-27.5 gr. Don't have any for the others.

I've done some searching and found a cast bullet mold maker which has some data for a 694gr Cast bullet in .50 Cal that may be similar to enough to the Matt's Hardcast that we can learn thing or two about what powder may be worth while trying in your load. Lil' Gun is near the top but H110 and it's brother Win 296 are listed as the top two powders. I manually edited the bullet from 694gr to 700gr to see if that would make a significant difference and it altered the results by about a .1gr or so. Listed are the results for the 700gr.

Cartridge COAL was assumed to be 2.300in
