RE: Various Hornady 240 Grain XTP Bullets
To throw another twist into all of this.. I've shot hundreds of both the .430 and the .452 out of different inline rifles. And not all rifles like the two bullets. In my Knight Rifles, they tend to like the .430 diameter while the Thompson Center and CVA like the .452 diameter. Also the 200, 240, 250, & 300 grain XTP's all seem to have excellent down range energy and expand real well....
So with many, its a matter of trial and error until you find the right projectile and the right powder charge.
