I've been reloading for a Savage Model 10 bolt action using Varget powder. I'm looking into getting a 16" barrel AR in .308 and wonder if there's a better powder for the shorter barrel? I'd like something that meters better as well. I've been shooting a variety of bullets in the Savage, but will probably stick with 150-155gr in the AR. I've used AA2230 in .223 with 50-55gr bullets with good results, and it's listed in my Lyman manual for .308, but I've never read about anyone using it. Suggestions? Wanna kill these ads? We can help!
