Dunno how the theory that CRF actions can't be jammed by short-stroking ever appeared, but it's BS. Have seen short controlled-feed actions jammed tight as hell by short-stroking.
Probably one of the better arguments for a 375 Ruger rather than the H&H. ('Skinny' cartridges are more easily bent in half to jam things up IME.)
.............. or at least that is true of the 223-based cases when I've put some coal behind the 'stroke'. LOL
Sometimes, the air you 'let in'matters less than the air you 'let out'.
