Cayugad,

When using the Pinnacle 3f, APP, what were your 50 yard groups like?

I wonder what the factor inhibitingaccuracy is. It seems to me that bullet stability is the primary factor, all other things equal. BP develops a higher spike in pressure earlier, which would help the bullet obturate earlier and perhaps more completely.I've yet to shoot ascorbic acid based powder with aconical heavier than 385 grains though I had intended to. Maybe I'll have to rethink that.

Happy Hunting, Phil
