I recently started playing around with tightening them up in the bore for my style of hunting and am super pleased with my results thus far. I just don't trust a bullet that loads this easily for hunting, But accuracy is AWESOME!
When you speak of Knurling to tighten the bullet up, will it work with a softer lead Conical? I have a few different Grease Groove lead bullets that start out plenty tight but end up loosening up a bunch about halfway down the barrel, I've thought about trying to Knurl them but just haven't done it
Knurling a soft lead bullet is not a problem at all. But I do not think it will solve your problem.
It sounds like your bore varies in diameter and unfortunately it is tighter at the top than the bottom. So even if you were to knurl the bullet the knurling would be sized to the tightest spot in the bore and in your case that would be at the top of the bore so by the time it reaches the bottom portion - it again would be loose.
