Ben when you nose size bullets. I assume you put the nose into the sizer first. Then push downward into the sizer to decrease the nose dia. Where does the displaced nose dia. usually go? Is it pushed ahead of the sizer? And does the pressure that pushes down on the bullet bump the driving bands larger?
I hope I'm not limited to the number of questions asked!
Just as a starting point. On a bore rider bullet what would the best dia. be. In starting load and bullet development? The throat dia., the bore dia., bore plus (.0005)
