I own a rifle with a long barrel, which gives it a higher muzzle velocity even when using factory ammo. Does the Aguilar System work for me?
I chronographed 175-grain Federal Match ammunition fired through a 34″ barrel and it was 2700 f.p.s., a hundred f.p.s. faster than it is through a 24″ barrel. I dial in 6.5 MOA when using this rifle in 500 yard matches. Holding on the second mil-dot as the Aguilar System advises would be 6.88 MOA. A difference of two inches at 500 yards is negligible.
