No I didn't even bother measuring the one from the breech as it fell out of the end of the bore when I tipped it up to get a better handle on the rod. I figured it would anyway by the way it felt.
Now it could be some fouling, but I can't see anything! I am going to try measuing my CVA tonight as I'm not busy and I'm interested if it is the same way. I'll also try to scrub up the breech areas just in case there might be some build up there and I'll also re-measure the KP1.
For whatever the reason, it's definatly narrower.
