I've got a rifle in .223 with a 1:12 twist barrel that shoots 69 gr. Sierra Match Kings in 1.5" groups at 100 yards, but I only get about 6" groups with 60 gr. Nosler pointed soft points (if you could even call them "groups" because they are all over the place. Now, a 1:12 twist .223 barrel shouldn't even shoot the 69's for crap because it supposedly isn't a fast enough twist to stabilize them.
Both loads were charged with 24.2 grains of TAC and loaded to the recommended C.O.L., which I believe is around 2.25" if I recall correctly.
I haven't tried the rifle with lighter bullets yet, but plan to pick up some 55 grain pills of some sort as soon as I can.
What's going on?
