And also another question, but I recall seeing a photo of someone actually chamfering the whole circumference of the chamber end instead of cutting the extractor slot in the barrel. Just looking at the drawings makes me think that the counterbore in that case seems kind of unnecessary as the chamfer seems like it would remove so much material that there would be no counterbore left. Am I correct or missing something and does anyone remember where the photo was located on this forum?

Date says 9-20-94 and Issue A (hex to the barrel end) is dated 3/7/97.
What revision or date is on your print ??
The bore says .235 x 0.8 inches deep, but a .22LR ammunition has a case diameter of .226, which means a .009 inch diameter difference, which to me sounds a bit large. So, is there an error is this some technical decision that has not been explained in the sheets of paper I have or that I don't know about?
Also would like to hear about the chamfering vs. slot cutting.

I think this is a safer and wiser approach. A split case is never a good thing anywhere.
Can't help with he slotting verses chamfering, I slotted mine.

Also the gauge dimensions would be nice to find somewhere, as I can make that one also at work.
Does anyone have good sources for these dimensions (go/no-go gauge & reamer)?

If you are unable to buy, perhaps one of the forum members could assist.
I will also try to look up the dimensions for the reamer and gauge, I have these somewhere.
