Post by: timberghost72 on February 04, 2011, 01:37:33 PM: Barrel length and rate of twist will help get an accurate answer

Post by: Straight Shooter on February 04, 2011, 01:45:32 PM: They're typically 1:9 like my DPMS ARs. My ARs will pretty much shoot anything 68 grs or less with great accuracy. Right now, I'm shooting more 40 gr and 50 gr V-Max loads than anything else. When you're talking about "best" grain bullet, are you talking about long-range bullet-drop, wind drift, energy, etc.? :dunno:
