We really do need more feedback from the OP.I am going to wait on the OP to report back.
On purpose.there is no way in hell a pistol manufacturer would cut a chamber this tight.
OP did post the problem was with both the case gauge and the barrel918v said:OP said the case gauge is the problem, not the barrel

9mm, resize/deprime, case plunks in guage and barrel. Prime said case, still plunks in guage and barrel. Expand mouth (more than needed), run through seating/crimp die (with no bullet) and case plunks in guage and barrel.
As soon as add a bullet to this process ('cept I back off on the flare to just enough to start the bullet), it must be forced into the guage and barrel.

Post #2 suggested measuring a fired, unsized round.I read post #35 to mean his round is rubbing the case gauge, not his actual chamber walls.
He won't disclose the fired case diameter which would prove the diameter of his round (and the bullet diameter) is not the problem.
He wants a lead bullet handload to pass a case gauge, and not to work as it should in hid gun. You are all assuming the actual chamber in his Kahr is undersized by something like .005" which is impossible. As much as I dislike Kahrs, even they have standards.
Yes but he also said when he backed off the OAL the case did not need go be forced into he barrel. He was perplexed shy the OAL needed to be do short.
No, not likely. A resized case would HAVE to be no larger in diameter than an unresized case. The unsized, fired case should rechamber without difficulty. So, a resized case should be that much easier to chamber. Until it gets bulged (either by insertion of an oversized bullet, insertion of a properly sized bullet where the case walls are over-thick or some other, as yet unexplained cause).If chamber was undersized, wouldn't the resized cases have issues without the bullet? No issues until bullet is introduced.
Great! Looks like it was the case of oversized bullets. Now, I would focus on identifying the powder charges that produce accurate shot groups while minimizing leading in your barrel.bangbig said:Got some .356" from MBC today. Loaded 3 rounds without changing anything in my set up. Plunk right in the barrel and slide EASILY into the case gauge.bds said:Looks like you may have gotten a box of .357" sized bullets. Let us know how the .356" sized bullets work out for your pistol/barrel.
The case from that round AFTER being fired measured .384, .388. and .390 from mouth to bottom. Where does that fall in the "chamber size" range???
