I cannot imagine how this thing could possibly affect the point of impact.
I used mine this morning for the first time and I LIKE it! I did have one single instance of an ejected case lodging itself sideways inside the shell...I guess 6.8 SPC brass just happens to be just the right length to do that. It wasn't a big deal at all, I was just a little baffled when after firing three rounds only two were in the hopper. A fourth round might have knocked that one stuck case loose.
I can highly recommend the brass goat.
