264, What lenght barrel do you have on your .264 and what is your fav. powder for that caliber??? Most of the better powders were available when I had my last one..
30" Shilen 1 in 8 twist and I have always used H4831.
Hey 264!
You've been hamstringing your .264 if you are using a relative "pistol powder" like H4831.
Try some of the slowest stuff you can get your hands on like WC-872 and your .264 will achieve its fullest potential
