Sighting in a new to me BlackKnight looking for load suggestion. I have some 300grain xtps in a green sabot and some 250 sst's to try wondering which of these or other suggestions. Typically shoot 777
My old Knight MK85 shot 300 gr. Barnes Expanders really well with two 50g.Pyrodex Pellets. Either of those bullets will probably work just fine, though. If using loose 777, I'd start off with 90 grains.
