My 317 HiViz has a real problem shooting CCI Stingers. After about 16 rounds or so I can't eject the spent casings out of the cylinder. It's like their fuzed to the cylinder walls. Regular .22LR rounds seem fine but it sure doesn't like Stingers.

Characteristic of the beast?

I think the Stinger has a slightly longer case and a slightly shorter bullet, so the OAL is normal. But the longer case would be deeper into the chamber and that might cause extraction problems.

I have a #317 that will do the same thing after firing about three cylinders full. All of the J frame rimfires I have owned have pretty much done the same thing. I get better accuracy with standard velocity ammo than high speed stuff.

Thanks for the feedback. I didn't think I was alone on this one. My stainless steel 617 will shoot Stingers all day without a problem. I can live with shooting standard velocity .22 LR on the range. CCI Mini-Mags work okay but the case material is different and that may really be the issue: dissimilar metals reacting at the higher temperatures generated by the Stinger round. Makes for a nice theory...

No brainer for me. My 2" 317 shoots erratically with any high vel stuff. Federal standard vel shoots much more accurately. It is very accurate at short range, <25', with CCI CBs.As I use for trainer for my J Frame EDCs, this is ammo I use the most. Now my Ruger Bearcat loves Stingers!

Does it lock up the cylinder? High pressure causing the cases to buldge?

The cylinder doesn't lock up but the cases do bulge enough to seriously stick in the cylinder. I've had one experience with the cylinder locking up but that was with some standard velocity Remington bulk ammo.

Not all .22 LRs can function with Stingers. I love the cartridge, but it is just enough different from other .22 LRs as to be quirky. When it works it is beautiful, but it doesn't always work. It also can be really erratic in accuracy in some barrels and a tack driver in others. I suspect the 317 with its aluminum cylinder is not one of the guns that Stingers will work in. Mine loves Federal Bulk and CCI Minimags. In a short barreled revolver you're not going to get the real benefit of the Stinger anyways.Even my Ruger MKII is not a"Stinger Gun", so it doesn't bode evil for the 317.

My conclusion exactly. I save the Stingers for my 617 or my BL22 level action.

There are basically three levels of .22 ammo,
Standard Velocity, High Velocity and Hyper Velocity. The Stinger falls into the Hyper Velocity category.

S&W does not recommend a steady diet of the Hyper Velocity in the 317. I mentioned this in an earlier post and here is the quote that I got from S&W when I wrote and asked if I could shoot the Hyper Velocity ammo in my 317:
"<STRIKE>You can shoot any of them but extended use of the hypervelocity can causes accelerated wear."</STRIKE>

An interesting note on another firearm mentioned here is that the Ruger Mark II & III both specify only Standard and High Velocity and omit the Hyper Velocity in their ownerer's manual. On the other hand, Ruger supports the Hyper Velocity ammo for their Sigle Six and 10/22.

The Federal bulk ammo does great in my 317 so I am sticking with it.

I think your Stinger problem is the same problem as shooting 357's AFTER shooting 38's.

The short regular 22's leave a deposit in the cylinder. When you follow up with the Stingers, the longer cases fuse to the deposits.

TRY THIS: Clean the gun. Then shoot the Stingers in the clean gun. I bet you will find that the cases extract without any problem.

I bought a box each of Velocitors and Stingers some years back - so I could get my wife the shirt they offered then. The shirt is long worn out - and may not even be in the rag bin. The two boxes are still here - most of the Stingers. They won't even chamber in any of my three CZ-452 rifles. I've shot a few of the Velocitors in the Ruger SS I had - they wouldn't chamber in the MKII. I do have only a 617 now - and may try them there. At least my wife liked the shirt!

I actually thought of that when I initially discovered the problem. I tried this approach...no joy. I even made sure there was no lubrication of any kind on the cylinder walls. Same result. I can shoot about two loads of Stingers before they serious freeze inside the cylinder. My conclusion: don't shoot a lot of Stingers out of the 317.

Though I must admit I still do shoot a few to make sure I know how they perform. I do this because in the early morning hours when I go out for a run I carry this light weight revolver with me. I live in a relatively safe neighborhood but we do have a bumper crop of Coyotes and loose Pit Bulls. The Stinger round gives me enough extra punch if I needed it. Most of my other "personal defense systems" are too heavy to carry during exercise.

The few times I shot stingers in any 22 I found the accuracy to be so bad I never used them again.
