There are several different types of snap caps available for .22 long rifle caliber. are the 3D printed versions adequate? they seem to be the most commonly available. I want them to dry fire my Wangler.

Ruger Wrangler owners manual
DRY-FIRING: Going through the actions of cocking, aiming, and pulling the
trigger of an unloaded firearm is known as “Dry Firing.” It can be useful to learn
the “feel” of your revolver. Be certain the revolver is unloaded and that the
firearm is pointing in a safe direction even when practicing by dry-firing. The
WRANGLER®
revolver can be dry-fired without damage to the firing pin or
other components.

As far as I know, Tipton is the only company that sells "snap caps" for .22 rimfire. The rest are dummy rounds which are not really designed to cushion the impact of a dryfire--at least not more than a few times. For example, Pachmayr sells some that they claim are good for 10 dry-fires before they need to be discarded, but I've seen at least one review that said the cap shattered on the first dry-fire. Some companies call theirs dummy rounds and indicate they shouldn't be used for dry-firing.

That said, per the manual, the Wrangler can be dry-fired without damage to internal components.

In my limited experience “Snap caps” usually have a cushioned spot for the pin to hit it numerous times. The dummy rounds are used to train a newer shooter on safe handling or to function check a gun. When dummies are hit by a firing pin it usually leaves a dent and makes it pretty much useless to cushion a firing pin afterwards.

Triple K .45, the center is spring cushioned. 4FDA71D9-7A6B-4DA2-9E12-82625257CEF1.jpeg CA08993A-31CE-4818-8076-4B673168CE94.jpeg

And a 12 ga shot-filled dummy for function checking. The head is solid metal so pulling the trigger for one “shot” will leave a permanent dent.

For rimfires, the wall anchor trick is the way I go about it too. :)

Stay safe.
 
Interesting.
I have always thought the problem with dry firing a rimfire was damage to the firing pin, not peening the cylinder.

It can be either or both, depending on the gun. I second the recommendation for using plastic drywall anchors. You can also just save your spent rimfire brass, rotating each case after a few strikes to hit a new spot.
 
Regarding the video posted by 243winxb.

1. The Wrangler needs to go back to Ruger. Something is out of spec in that gun.
2. If you have a peened rimfire chamber, don't file the burr off, buy a chamber ironing swage tool or go to a gunsmith who has one. The tool will push the peened metal back into place which is a better solution than removing it with a file.
3. Using spent brass as a snap cap in a .22LR will work a time or two or three, more if you rotate the case so that a new portion of the rim is presented to the firing pin each time. Otherwise, it's going to flatten out with repeated hits and stop providing any cushioning effect.
It can be either or both, depending on the gun.
Correct. That said, the prohibition generally stems from chamber peening. Rimfire firing pins are pretty sturdy; they have to deliver more of a blow than centerfire pins in order to set off the priming compound in the rim.
 
View attachment 1130089 I bought some of these for dry firing.

I paid $8 for the pack.

They’re aluminum. I would turn them a bit after a couple of hits then once the rim was all cheesed up I bought more.
I really don’t like dry firing my guns, snap caps or no. I only bought them to try them out and keep my trigger finger exercised when I was out of commission for an injury.

Your A-Zoom package says right on the front, "NOT DRY FIRE SNAP CAPS - SEE WARNING ON BACK". Use the drywall anchors instead...they are cheap and they are made of plastic so neither the firing pin nor cylinder get a beating. For $8 you will basically get a lifetime supply of snap cap/drywall anchors.

Be careful with those, it says in red right on the front they’re not snap caps :eek:. I’d hate to see you get a chamber dinged.

Stay safe.
 
Thanks. Will the yellow anchors work on a .22 magnum or will they be to loose?
The spent brass is a good idea too.
 
I also use the #2 (yellow) drywall anchors. The rims will flatten, so rotate them around in the chambers like you would with a spent case. I have also manually cycled them through the magazines and actions of multiple firearms.

I haven't tried them in a WMR. I expect they would be loose; the rimes barely reach out as it is in a LR chamber.
 
Using spent brass as a snap cap in a .22LR will work a time or two or three, more if you rotate the case so that a new portion of the rim is presented to the firing pin each time.
That's what I do. Good for 6 or 8 firings per empty. More if you want to be more careful about how much or how little you rotate the brass.

Tipton makes a .22 that is explicitly a Snap Cap not just an action proving dummy. All translucent plastic, comes in a 25 pack for $12.

Q&A on their site:

"are these safe to use for dryfire?"

Customer Support:
"Yes, that is the purpose of them."

Those are NOT safe to dry fire. I learned the hard way as I am currently replacing my heritage 22lr cylinder. A $30 lesson so it doesnt sting too bad.
 
This plastic rims chip away and then you hit the face of the cylinder. I will upload a pic later.
 
I don't dry fire my .22 guns. But I do fire them using a dummy round . Usually a dry wall hanger. I do make sure I rotate the dummy rounds every few pulls to keep from wearing down the plastic rim which can allow the firing pin to contact the cylinder
