So lets talk 10/22's again

But it's quiet even without.

With subsonic ammo and a suppressor, the only sound you hear is the slide/bolt cycling.

But it's quiet even without.

you start to think 22s are quite due to wearing hearing protection and comparatively to other larger calibers at the range but go shoot a 22 in your backyard in a suburban neighborhood and i'm pretty sure you will say oh shit, oops and run back inside.

[CJ]

What's the point in having a suppressor on a .22, anyway?

It is the only caliber which actually gets near silent. No other caliber suppresses as well as .22. I use my .22 for hunting rabbits and other little animals. When my gun is quiet, they don't run around as much and I can kill them easier.

[CJ]

Tolerances or clearances?

Tolerance is proportionate to clearances, either or. Tighter the action, more often it jams.

It's been awhile since I've shot one, but I seem to recall the sound being less than that of a black cat.

Gotcha.

I've always thought they were two different things. Like the clearance is the actual spec, and the tolerance is the acceptable range in variation. So a tighter tolerance would mean +/- .001" off spec vs +/- .005" off spec.

Yeah you're right, when you decrease clearance you make the tolerances tighter (or smaller). Smaller clearance means less room for variation.

You could build a part with loose clearances but with exacting tolerances.

[momo]

i am clearly not tolerating any of this nonsense.

[Trick Pony]

Tolerances don't necessarily have anything to do with clearances. While it is true that when there is less clearance, generally tolerances HAVE to be tighter for things to work properly; it's not necessarily true the other way that just because you are machining something to tighter tolerances, you are going to reduce clearance.
I would seriously doubt that the dimensions of the receivers are different, they are just made to tighter tolerances meaning anywhere you measure on the part will be off compared to the intended dimensions by a smaller amount compared to a part machined to looser tolerance. This results is parts that are truer, lines that are straighter, surfaces that are flatter, etc. Changing the actual dimensions of the part would be undesirable for the reasons CJ mentioned.

see i would think that's not correct. i think if you purposely decrease clearance you've changed specifications, having nothing to do with your toleralance.

your tolerance would be your adherance + or - a measurement from zero as defined by your specifications.


lets say you and ruger both make a receiver and for shit's sake you both use the same specifications.
you are both trying to have the exact same clearanced receiver but the only difference is ruger used their cast aluminum process which has a +/- .1 mm accepted tolerance range and you cnc laser milled a receiver from a block of billet aluminum with tight tolerances of +/- 0.01 mm.

now you put both of these receivers next each other and took measurements.

you find that your barrel lines up at 0.01 mm left of center and their barrel lines up at .1 mm left of center due to process. now since both of these are within your accepted tolerances you roll them out and sell them.


NOTE: this is the stupidest thing i may have ever written considering i know nothing about casting aluminum, cnc milling, or the processes behind them. i am stanleytweedledumb's insane half twin.

You guys seem to be missing what I was saying. I was saying if you are decreasing your clearances, your tolerances are going to need to tighten up, because there is less room for error. If you go from .010 to .003 on clearance, your tolerance can no longer be ±0.005, it must be ±0.001. So thereby if you decrease clearance, you must tighten up tolerances. No need for all the cerebral contemplation. They do have an effect on eachother

Brilliant.

Clearances are dimensions, tolerances are deviations from those dimensions
