OK John. Here's what I came up with. My method differs a bit from yours because you have to allow for the thickness of the bolster when you insert the wire. The width of the breech including the bolster is 1.467. The breech itself is 1.265. So the bolster projects .202 from the side of the breech. The wire measured .859. Deduct .202. for the bolster and you get .659 to the FAR SIDE of the exit hole. The dimension from the outside of the breech to the CENTER LINE of the exit hole is .6325 (the width of the breech without the bolster divided by 2). That would suggest that the clean out hole extends past the exit by .0255 BUT that's not really the case because the wire went to the far side of the rather to the center of it. To sum up, I don't think there's run out of the clean out hole. And, when I shine a light on the exit hole, I can see the end of the wire hit the side of the exit channel. Granted, I'm not the best guy with a dial caliper, but I think I'm close.
Thanks for your suggestion. I actually thought that I was going to find the problem.
Regards,
Duane Spyer
