This is something I don't understand 100% a .45acp is not know for deep penertration but with a 230gr. hornady xtp/xtp their catalog says deep,terminal penetration whats say 4.5 grains of titegroup how can that be with so little powder to power the bullet? Now with a 44 mag you would get more penertation with alot more powder and the same bullet.....right?
