I have loaded 40 to 60 Gr bullets in both .222 Mag and .223 over the years, but never had a barrel faster than 1 in 12 twist until I bought an AR with a 1 in 9 twist, and even then I did not try anything heavier than 60 Gr.
I just ordered a barrel for an AR with a 1 in 8 twist Wylde chamber and if I have read correctly, it looks like the 1 in 8 will stabilize up to the heavier 75 & 77 Gr stuff. I will be shooting some 50 & 55 Gr stuff, but also want to try the heavier bullets. I have a box of 69 Gr SMKs, and am willing to try other things as well.
I would appreciate folks thoughts and insight on what your favorite bullets and powders are, especially when using bullets heavier than 60 Gr.
Thanks, AC
