I have some friends that can't seem to find their calibers that fit them. Maybe they just like change. I prefer the for sure know it like the back of my hand when it comes to making it as painless as possible. I use only three rifles. 22-250, 300 win ,and the ole underated 270win. Tragectory wise they all are shooting less that 5 inches of drop of eachother at 500yds. Darn took all the guess work out of the shooting. Hmmmmmm.

Velocity = ftlbs beyound 300 yds.
