I never measured them but they are not slip fit my any means. At least not in my CVA Staghorn Magnum. When I shoot Powerbelts, I can push them under the muzzle line and then seat them with a ramrod. Even after shooting a few of them. With the Sabre Tooth bullets this was not the case. I needed a short starter to drive them into the barrel. On a fowled barrel I even had to get out my Thompson Center Rugged Range Rod to seat them for fear of causing damage to the flex rod I normally use for range work.

The accuracy was exception with them but of course I was not shooting a long distance.. I want to try them in some different rifles and at different ranges. I was hoping some place would put them in sale so I could pick them up cheaper still, and get some of the different sizes...
