I reload for all of my guns and use cast bullets for the old timer S&Ws and Winchesters. Of late I am having a lot if issues with bottle neck rounds for my 30-30 and 32ws. Seems like after full length resizing the case fits into the chamber perfectly, but after the bullet is pressed into the neck it will not chamber in the Winchester lever guns. I have checked the AOL and its within specs. What's happening and how do I fix it. Thanks for your help.
