the new 6.5 Grendel build is making bullets tumble. any help would be greatly appreciated!
i have never put together and AR that didn't just run. so this is new ground for me.
for the build i used a Black Hole Weaponry barrel 1x9 (checked this and it is indeed a 1x9 twist) i do not have a muzzle device yet.
the load that i used is 36grs of H335, 120gr Vmax, hornady brass, Winchester primer.
(used Redding FL dies)
any help or suggestions would be great!
thanks again!
