Re: Which First Bullet Seating or Powder Charges Reply #15 – June 30, 2020, 04:28:14 PM Quote from: bikemutt on June 30, 2020, 11:12:29 AMThis sounds suspiciously like a problem I ran into. My brass had developed a donut such that even fired brass would have "feel" when lifting the bolt (firing pin and ejector removed). It got worse; bumping the shoulder 2 thou still had the same feel. Just to be clear, this is without seating a bullet, it was just the brass.I'm no expert but you shouldn't have to seat regardless of true CBTO unless you are up against feeding constraints.I agree on your point of a stiff bolt with fired brass. But first, I forced the bolt close to chamber a live round. Figured that was not a good idea to shoot the round because of pressure considerations (shouldn't have to force it into the chamber). THEN I had trouble lifting the bolt and unchambering and ejecting on a live round. It took a lot to get it out the chamber. I will not force another round like that again. Learned my lesson.
