I bought a Werndl carbine and thought “what a perfect bore”. Now it appears to have been rechambered and rebored but never shot. Definitely not a wall hanger any more if I do everything right, but I have never done anything like this before, so I am going with my empirical knowledge, I will start with the bore slug. I used a .452 SWC, the lands made a good cut and the excess lead started to fold over onto the groves, however, the groves never formed and gases will pass in front of the bullet. Do you think a solid pure lead .454 or a .458 will do the trick to create a grove or should I go with a skirted, back in the day I think a 300 grain pure lead bullet was used.
After a bullet is determined I will explain how I came up with a viable case, I think?
