Need Data for Black Hole Barrel using Hornady A-MAX

[NugginFutz]

Well, as always, YMMV. Please take time to check pressures during a load work up from safe starting weight. This statement has not been evaluated by the FDA and is not intended to treat or diagnose any diseases or illnesses.

Ok - my 22" BHW barrel really likes 28.2 gr IMR 8208 for those 123 gr A-Max pills. I use Hornady brass, CCI450 primers, and seat at 2.260". Groups are consistently 1/4 - 1/2".

MV @ 10' is 2600, and SD's are in the low teens.

Dope to follow...
