Deforming the ball is the usual result of hitting the Ramrod, or "bouncing the ramrod" on the ball to seat it. It makes little difference when shooting at 25 yds. You can see the groups open up at 50 yds, and at 100 yds, you begin to ask, "what group"? A good friend of mine bragged about bouncing the RR off the ball to seat it to his ' mark" rather than clean the barrel of his .45 between shots. He liked to slam the rod down hard enough that it bounced Out of his 44" barrel. Even from a bench rest, he could not get a group at 50 yds, and rarely hit the 12 x 12" target out at 100 yds.
What you are doing now,- lowering the ball by hand over hand to your mark, works much better to get accuracy, IMHO. Other opinions will vary, of course. :surrender: :thumbsup:
