I am very new to the shot shell scene. I'm working off an old MEC Jr. and loading 00 buckshot. I also added the newer Spindex pre crimp, which helped slightly. When I load using Win AA's, I am having moderate success. With Federal Gold Medal, I get swirls every time! I've adjusted my pre crimp, I've tried adjusting the final crimp. Its the same every time. Any help at all would be appreciated.
Sorry for the rotated picture.
