This was my first test of blackhorn and first with Federal BOR slugs.
So I weighed out 70 grains of black horn on a scale and made up some speed loaders for the range. I used CCI shotgun 209. Rifle is a TC encore with SS barrel. Scope Bushnell 3x9 3200.
Anyway the first shot was way right of the group. Then I shot 6 more at 50 yards, and the group was fist sized. So I was not that impressed. I could easily get a better group at 100 with TC shockwave sabots and 3F goex. I will say loading was insanely easy even on shot # 7 with no swabbing between rounds.
I guess Ill weight out some 60 grain loads of BH and give that a test. I also have some 348 grain powerbelts so I may give them a try with blackhorn.
My standard load is 240 grain shockwave and 100 grain 3F GOEX BP, but I could not find shockwave locally so I feel like experimenting. I don't know how much testing I will do with the federal slugs in this barrel, they are 25 bucks for 15 rounds. I think I was getting 20 or so shockwaves for 5 bucks after season clearance at walmart, so the cheapness factor is in play. If the 60 grain BH + Federal slugs shoot as good as the shockwave, I would switch to the new combo even at the $$$$. I actually shoot flintlock, so this is a side game for me.
