I have indicated on several barrels that were damaged or poorly designed, and cut a radius into the end; and changed the rifle all for the better!

I'm messing with an old LaBelle, and due to similarities; I may convert it to a 30-30. You speak truth on the ballistics on this round. I kind of group it with the ak and Enfield rounds. They seem to behave a lot alike (even though the Enfield is my Son's favorite rifle) and seem to be more for limited ranges, less than 500 yards.

This does Not mean they are inferior, just different. I have several 30-30 (30 calibre with 30 grains of black powder originally), and enjoy shooting both! The original black powder round would have been even more under powered....

This article added a variable I didn't know about, thanks! I wonder if there is a spin balance for ballistic points, to pre test projectile balance before re-loading?
