The busters i used that went thru the shoulder had no such deformity issues at all and have the same base to crimp groove distance so they were very very easy to get to hit the same point of aim. The busters worked really well but im kinda stoked to have a round like the aframe that is capable of expanding on deer and elk but also in taking a cape buff. I loaded one a frame followed by 3 busters for odd angle follow ups
