Thanks for the report on the A-max. Many don't know that Hornady lists in their manual that it's suitable (in some weights/calibers) for medium game.
I've thought about trying some myself. I've gotten good results from some Rem. 120gr SST's (MidwayUSA blems) and similar load.
My rifle though has a 1/10" twist and won't shoot well (6-8" groups) with 129gr SST's, and won't hit target at 100yds with 140gr SST's.
Exit wounds, penetration ??? Recovered bullet ?
