My 1:8 Black Hole has never liked heavies. 73 ELD’s, 75 HPBT’s, 75 A-Maxes (cut the front out of the mag), none of them. Never tried any non Hornady offerings.
It did fairly well with Sierra TGK’s.
Lately, it’s just been fed 55SP’s and 53 V-Max’s. The 53 is pretty amazing in my rifle.
Might be worth mentioning that BHW uses polygonal rifling in their barrels, which could have something to do with its distaste for heavies.
