Quack, I had Single-Sixes come into my shop with the owner's complaint that a 22 LR would not chamber. There were a few cases where the cylinder was actually a 22 Mag but it was so fouled that a 22 LR couldn't be forced to chamber, let alone a 22 Mag.

Montana09 is convinced he has a 22 LR cylinder so we have to believe he got ahold of some really crappy ammo.

In the mid 80's I was shooting some Federal ammo in a Remington 22 Fieldmaster 572 rifle. I had some rounds that were much louder than a 22 cal. Each brass had the rims split but this did not go the length of the brass. Federal wanted the spent cases and ammo I had left. Then they sent me a brick of 22 ammo plus the dealer that helped me got a brick.

I'm convinced the OP's cylinder is a 22 Mag and the reason why he can't insert 22 Mag cartridges is the chambers are badly fouled from shooting 22 LRs.
Yep, I agree with Iowegan. Rod

This has really been a strange one. From all my 50 some years of shooting Single-six revolvers, it's hard for me to understand a .22 long rifle case splitting from the rim clear to the mouth in a .22 long rifle cylinder, but the OP is very clear that it isn't a .22 magnum cylinder, so just have to chalk this up to a very unusual experience with a bad batch of ammo.

In 65 years shooting old .22 rim fires I have seen some split ruptured cases rims.
I haven't experienced this in a long time.
A Gunsmith wit go no go gauges or one of a few gauges can tell but it sound like the chambers are too large.
If you can drop a cartridge into a clean chamber and it rattles around or is obviously real loose the chambers may be too large.
Brass case .22s stretch quite a bit so to split has to be too much clearance.
Unless there is a production run, of unannealed after forming .22 cases, possibly.
Too many variables without examining the gun and cases and some unfired shells from the same batch.
I would try an entirely different brand of shells and,if they split then it is the cylinder.

I had trouble with the Remington Golden Bullets rupturing the
rims in my USFA 12-22 and locking up the cylinder. It was difficult
removing the cylinder to clear the problem.
