Thanks Ramrod, can you explain the seating process a little further for me please? Are you saying that you intentionally seat one too long and then put some soot on the projectile, chamber it, then see where the rifling marks start on the soot and then seat it to the depth where that mark will just be starting in the lands of the rifling?
Yes that's what he is saying. But here is something to remember is that most factory guns have a long lead to the rifling for lawyer reasons and that seating a bullets ogive just off the rifling is probably going to be too long to be magazine fed, and would cause you to single feed each round.
