suppressor ammo

[DrBaker]

I have the Outback II .22LR suppressor and I've been using Federal Champion (cheapo 500rd blue box) with it. I haven't had any problems at all. I didn't realize until recently that the Federal ammo was high velocity. The owners manual for the can suggests using standard velocity ammo. Should I be concerned about changing to a different ammo?

Standard velocity is slower than the speed of sound, so you do not get the report. But using high velocity shouldn't hurt your suppressor just not getting full
benefit of it.

That's what I was thinking, but wanted to ask before I fired the bad shot.:nolike:


With ammo prices being so high, it's great to buy a 500rd brick and be busy all day.

True that I shoot more .22 than anything else even target or good .22 amo is half the price of Blazer 9mm.

Most HV ammo including MiniMags would still be subsonic in a short pistol barrel like on a Walther P22, but you need to run standard velocity in a rifle like a 10/22 to get the maximum effect. The HV stuff won't hurt the Outback II, but it won't be as quiet as ammo that stays subsonic.

I used it in my P22 and 10/22 at H&H and they were both silent. I assume the Ruger was silent because of the short distance??

CCI GreenTag compitition ammo.

Cost a little more but DANG it works great with suppressors.

Yup - an indoor range can be deceptive when it comes to the difference between the audible crack of super/sub sonic ammo.

I have a P22 with a Tactical Innovations TAC 65. The regular (high velocity) ammo that I run through it is CCI Mini-Mag. The subsonic ammo that I use is Aguila SSS Sniper Subsonic. These are basically a .22 short case with a very long bullet that gives the round the same overall length as a .22 long. When I first bought these I was afraid that my P22 would not cycle with them (it's a pretty particular about ammo). But they run 100% in my gun.

The SSS Subsonic is sold at Brigadoon Military Surplus in Midwest Shitty (close to Tinker). And when you shoot these outdoors, there is NO supersonic "crack". It is scary quiet. My wife's farts are louder...

There is an issue using the SSS rounds in a suppressor. The long bullet does not stabilize in the slow twist that almost all .22 rifles and pistols have. My Gemtech Outback II manual specifically mentions that using the SSS rounds may cause baffle strikes and will void the warranty. Tactical Innovations makes a 1:9 twist 10/22 barrel just for this round (see link below), but I don't know of anyone making a P22 barrel with a faster twist.

A little off subject, but CAR-AR-M16 what is your cleaning procedure for your Outback II?

So far I have followed the manual for chemicals and timelines (actually cleaned a little earlier than what they recommended). I was told to use Kroil, but haven't gotten any yet. I was planning to order some soon. The manual doesn't mention anything about the use of Kroil. I've heard that the Kroil stinks when you first shoot after the cleaning. Any other recommendations?

Thanks VERY much for the info! I've shot a few hundred SSS rounds without incident. Guess I've just been lucky.

I really don't clean any of my suppressors. Any carbon build up will blow out when it gets thick enough. Nothing will remove the lead that won't also eat the aluminum and I believe any solvents just attract more crud. About the only thing I do is blow them out with some compressed air. Dr. Dater from Gemtech used to tell people to clean their suppressors about as often as they clean the muffler on their car. A .22 sealed suppressor will eventually build up with lead and need to be rebuilt, but it will take a lot of rounds to do that.

Will Gemtech rebuild my OutbackII for a fee or would I be out of luck once my can reached the end of it's lead filled life?

Yes, Gemtech will rebuild it when it is full. I believe it is about half the price of a new can, but you basically get a new can with your serial number on it so there is no additional paperwork or taxes. Don't worry too much. It will take a LOT of rounds to fill one up.

Here is a link to a thread on ar15.com on the same subject.

I didn't know they would do that. That's awesome. I'll do my best to fill er up so I can test out the Gemtech customer service.:contract:
