Another DA Ruger question

[wow6599]

If I have my .005 feeler gauge between the B/C and dry fire all 5 chambers are untouched, if I do this with a .006 2 of the 5 chambers (cylinder) bind it up. So, I guess it's not perfect.....does it need to be, or should it be.

Here are the measurements (play) for all 5 chambers of the cylinder -

1) .003-.006
2) .003-.006
3) .004-.006
4) .004-.006
5) .003-.0065

Thoughts?

Found a feeler gauge in the garage

Nah, I'm just a perfectionist when it comes to to revolvers......and 1911's.
I just figured it shouldn't bind-up on 2 of 3 chambers, unless that's acceptable.

wow ~

Someone with way more knowledge than me will likely come along with a serious answer for you. Temps here are in the low teens so I'm spending way, way too much time on the internet.

Happy shooting!

If you asking if a .0005 variance in where you measure the B/C gap is acceptable, the answer is yes. A lot of 6-guns will vary 2X that amount.

Your gun has a nice and tight bbl gap, and thats a good thing. Less than .003 or .004" and you might bind up during firing especially if the gun is dirty. More than .015" and you might get some "spitting" through the gap when firing. 2 chambers binding is going to happen almost all the time when you use a shim that is at the mean or median of the bbl gap. This is due to the axis that the cylinder rotates on and the perpendicularity of the muzzle end of the cylinder. If the axis tips up or down, then then bbll gap will seem to expand or contract as you rotate the cylinder around that "cockeyed" axis. Likewise, if the face of the cylinder is ground a little crooked, it will do the same.

Long asnwer short, your cylinder seems to be rotaing around a pretty true axis and has an in-spec bbl gap with less than .001" of variation at the b/c gap.

Record these numbers & check em at 500,1,000, etc. rnds fired !!!

I do !! Index the cyls so ya can keep up with what`s where , I made a drawing of the "S" stamp & use it .

It monitors wear of forcing cone cyl face, recoil shield ,& ejector. & alinment of crane to frame .

You`ll see some opening up up to 500 rnds or so then it`ll stabilize & become very slow !!!

You have to go by feel of drag or some very expensive "feelers"!!!

What worries me more is the index notches & latch wear stoppin the heavy cyl. !!!
