The difference seems to be the 'taper' of the bullets used. If tapered the Ruger will chamber; if 'rounded' it hangs up just in front of the rim. Of course I don't force this.
Is this a case where the bullet is engaging the rifleing of the barrel on it's curvature?
It sure sounds like that's your problem. Are you seeing marks from the rifling on the round nose bullets?
