Has anybody run a test between the two with the same loads?
I've read that they're interchangeable, no accuracy loss with the cannelure. I've got 1000 of the 77Cs and I'd like to use some up in my fire-forming load for my 223AI, I've shot them in my 223Wylde SPR and they've shot very well 5rds at 100:
3 rds at 300, stopped when the bolt head flew off:
I've got a what's looking like a decent load, in the middle OCW test, and it'd be great if I could just swap the 77s.
So has anybody tested them? Same accuracy, MV, POI?
