Hunting Shack and thier 55 gr V--Max!
Negative ghost rider.......1:9 will not handle anything. I am by no means an AR whiz but I do have an AR with an 18" barrel 1:9 twist. I took the above advise and wasted money. My 1:9 will not stabilize 75 grain bullets. It will however stabilize 50, 55 and 62 grain bullets. It like the 55 grain the best and will hold sub 1/2 inch groups at 100 yards, literally stacking bullets on top of each other. The 75 grain Hornady V-max Match ammo will barely hold 4" groups at 100 yards. If you don't believe me....I have 200 rounds of Hornady Match 75 grain ammo for sale. Stick with 55 grain and you can't go wrong. They will destroy anything you will be shooting with an AR and are readily available.
I have always had the best luck with under 60 in my 1:9 twist rates. If I am shooting anything heavy I go to 1:8 or 1:7.
If you dont mind me asking, just out of curiosity, which AR did you purchase? I just got my first one yesterday ADDICTION!!!
Someone should warn the coyotes that I'm comin'.
