52 anything in 223=
25.8 grains Benchmark for 3400 out of a 14 or 12 twist.
Accuracy load is 23 grains of LT32
Max of 335 also works
Max of Vargay also works
Max of H-380 works but is a pooch for speed
H-322 works
AA2015 works
Bunch of others, but don't have access to my records right now.
I actually prefer 52 SMK and 52 Custom Comps . Hope it helps you a little.
Oh, BM and LT 32 will work real well in the duece also.
