I looking for advice/recommendations as to a good AR-15 for primarily coyote hunting during the winters. I like the looks of the Rock River Arms Predator Pursuit Rifle. I would like to use 55 grain bullets, (probably try VMAX's as long as they group well, otherwise some other 55 grain variant). My main concern with the Predator Pursuit is that is comes with a 1:8 twist. I know this faster twist is nice for heavier bullets, but wonder how accurate it would be with 55 grain bullets. Would 1:8 be fine or would I be better of with 1:9? Also, I would also like to use the AR-15 combo at the range shooting longer distances so great accuracy would obviously be nice. Thanks for any help.
