Bullet wt for 1:9 twist 223

[Varminterror]

I've killed hundreds of coyotes and thousands of prairie dogs with the 50grn V-max from 1:9" 223/5.56's.

FWIW the 53 gr Sierra Match King (#1400)is lights out in my 20" 1:9 ARs

Havent tried anything else but 55gr FMJ by RMR in mine. Seems to run just fine, want to experiment a bit soon with a little heavier combo.

Try the 55gr blitz king. It works good for varmint. If you're looking for top accuracy anything between 68 & 70 grains works well for a 1 in 9 twist. Look up the Greenhill formula on Wikipedia.
