don,
I still can't get over the fact that your bullet did not bump the bore ride section into the rifling, particularly with the pure lead composition.
the question arises as to whether your wad stack is absorbing some of the shock when you light the fire.
I tend to use only one wad, either plastic or vege, amd get serious bumpup even with 16/1. I would expect rifling marks to the front of your patch.
you must have a fine balance to leave no marks on the nose, yet get good confetti.
the o.d. creedmoor guys seemed to prefer one card or paper wad, and claimed to bump up 13/1 and even 11/1 with no problems, and my experience has been similar.
in fact I have gone off bore riding greasers for this reason.
possibly I should try softer wads with them.
Kenny does not patch as far forward as I need to, and he uses a massive wad stack.
a picture is starting to form. right or wrong, who knows. another can of worms to unravel!
keep safe,
bruce.
