K-22 sticking brass - do I need a reamer?

[vinn]

there is a reamer and a target reamer for .22. good to have both.

I bought two cartons of Aguila back around 2008 when .22 ammo dried up. I should have spent the money on one carton of good ammo! I had lots of sticky extraction and failure to fire in all my Smith revolvers. I can't remember if I shot it in my 41, but I doubt it. I will not buy any more, no matter how tight things get.

The cases would not have to weigh less. All 22 lr cases are thin compared to bigger caliber. All that is needed to make the case expand too much, and stick is more pressure, or a slightly different geometry round. 22 lr is notoriously dirty, so in combination with a close tolerance chamber in a target gun, and more expansion to the case... and there you have it.

Aguila .22 Super Extra is a fairly high velocity for a 22, compared to SV. You need more pressure to propel a 40 grain round to 1,255 fps than the typical SV round. More pressure -> more case expansion -> more likely to stick in a dirty chamber.

And btw, I have some, from Cabelas. They stick a little in my Model 17 and 18, not as much as the OP reported though. They also occasionally fail to extract in my Model 41, but that gun is notoriously finicky.

I'M the OP. My Aguila Super Extra is SV at 1,130 fps at the muzzle. 40 grain lead not plated.

If you can afford the reamer, and if you are half-way mechanically inclined - get the reamer. You will be glad you did. Everything else is a band-aid.

I have read a lot of old threads on the finish reamers and it appears that some forum members have loaned or rented them in the past.
I have tried to buy one from Brownells but they don't have them and don't know when they may handle them again. I only have the one K17 that needs reaming. If anyone has a finish cylinder reamer that I could rent or borrow, I would really appreciate hearing from them.
Thanks

Even though the Aguila brass weighs as much as other brands, it may be a different alloy and lacks the springiness of other brands of 22 LR.

Since it is only Aguila 22 LR that is sticking in your revolver, I would leave the chambers alone.

Here's an option if you decide to finish ream the chambers.....

If you only have one revolver, and dont plan on others, you may just want to let a good gunsmith do the job...cost will likely be close in $$$.....you wont regret doing it IMHO
