I just bought a Ruger birds head vaquero 45 ACP and I went to go shoot it for the first time with my hand loads and their semi wadcutters and the rounds won't fully see in the chambers. The bullets function fine in my Polymer guns and my 1911's. There's about a millimeter left that the bullets need to go into the chamber So it seems that the edge of the wadcutter is were the bullet is seating in the chamber. I hope that makes sense. Should I start messing with the crimp? Crimp is .043
