Rifle (re) build: Going full F-class

[Tim s]

Simple: If the chamber is tight enough in diameter, short enough in length, and/or is installed in a barrel with a tight enough bore or heavy land/groove ratio...the barrel has more purchase on a chambered bullet than does the casing itself.

So, a guy tries to remove the unfired round, and it simply UNseats the bullet from the casing and extracts the casing only.

Long closing cam actions that can be chambered really short can see the worst of it, if the smith sets them up that way with a reamer like the Nevius that does not cut the rim.

While I don’t disagree on questioning a full on no taper match chamber
If one is needing to feed from a magazine, I doubt you’d ever pull a slug out of a case on extraction. We have done several fully engraved ones out of older Benchmarks that went down to .215” bores. It’s pretty hard to pull slugs out of cases.

Every .22 lr rifle I have owned didn't have an extractor system capable of holding on to the unfired round if it was stuck from the chamber being too tight and I never seen a bullet get pulled from the casing while trying to un-chamber a unfired round. wonder what rifle/bolt has a claw with that much grip?
