I just bought a box of these to try out. 60 grn, 22 LR, sub sonic. I believe the MV is just under the speed of sound, something around 1050 fps.

Amazing penetration! It went through 2-2x6s and lodged into the 3rd. Next, it went though a 2x6, a piece of 3/4" maple and lodged into the last 2x6 producing a bump on the back side.

Supposedly, the twist on a 10/22 is too slow to stabilize it but I've shot it with acceptable accuracy, no key holes, with the Ruger, a Winchester pump and a S&W Model 17 6" bbl. It is significantly quieter than a standard 22 round. Pricey @ $50 for a box of 500 but if all you have for a self defense weapon is a 22 LR, I'd consider using these.

Aftermarket barrels with 9 1/2 twist are available specifically made to use with this round. I'd suspect that would be the ticket if you are really into hunting with a 22 or need one gun for double duty. Reports are that accuracy improves greatly with the quicker twist as is the case with heavier CF bullets, like the 70 grns for 223.

Also, it supposedly is used with great effectiveness on small game animals and proves to be more of a stopper than the light weight, higher velocity 22s.

I am curious about this round as well.

My old Mossberg .22 would not stabilize it. It was sideways at 15 yrds.

Bought a 22 conversion for my AR. The barrel is a 1:9 twist, so in theory this should be a good match.

Wierd, from a rifle with a 26" barrel it barely went through 1 2x4 for me. You have some soft wood.

Idk about the penetration. I've been using this stuff for a few years in a 10/22 with good accuracy up to 30yards. After that they drop like a stone.

2x6 was douglas fir and the maple board was dry and very hard. Having been in the wood business, if doug fir or white fir or southern yellow pine is dried it can become case hardened so much so that it has to be pre-drilled before nailing. Hardest framing lumber you'll ever work with!

I think the round was developed to be super quiet, especially when using a suppressor, under the speed of sound, and having the 60 grain bullet it should increase the penetration. Being a rimfire, it fills a niche for suppressor users. Reviews have it fairly deadly on small game but, yes, with that kind of velocity and bullet weight, it would have quite a trajectory. I bought it to kill critters in my back yard, raccoons, coyotes, etc., without upsetting any neighbors. I can reasonable shoot up to around 60 yards before hitting the brush and trees. It's an intriguing little cartridge but costs almost as much as my 9mm and 38 handloads!

Have shot some. The long 60gr. bullet looks funny. But haveing shot it in several handguns it was pretty impressive for a .22. Fired them into wet phone books. They went deep and turned sideways very quickly in the phone books. While traveling sideways for awhile it held together and bent into a "c" shape. Made a much bigger wound that the other .22's I've tested. Would be great for a suppred weapon.

The 26" brl is way too long for this round. What is happening is that it is running out of steam and then coasting/draggin and almost falling out the barrell.

I read a story in a gun mag not so long back where a firearms instructor detailed the use of this round in a self defence application against an attacking dog.

Apparently he was called in to speak with the investigating detective because the cop didn't believe the size of holes in the deceased mutt could have been caused by a .22LR.

But they had, and it was all courtesy of the 60gr sniper load.

My father has shot many feral dogs with lightweight .22 LR rounds. None that I know of caused immediate incapacitation. Good hollowpoints are sure death in the long term though. Entire packs would kill his chickens on tie cords, not eat them just kill them for sport. If you load the average sized dog with (10-15) CCI Stingers it wont get very far. He only used the 22 in a pinch. The Remington 1100 12 guage with 3" mags and a full choke throws the anchor out on a 50 lb animal out to really impressive distances.
The only KO I have seen is when I put a 60 grain SSS aguila between ones eyes. All of these examples are from the same gun a Winchester model 74 semi auto rifle. This dog never felt a thing. He was dead before he hit the ground. He exhaled one hard puff and pulled all four legs up under him off the ground. He slammed the ground and never quivered once. Massive bleeding from the ear and nose ensued. It was a humane kill.
This is one of my experiences with this round. I have pet dogs that I cherish (among other pets) strays are a threat to their safety and mine, so Im not really trying to get moral opinions on exterminating stray animals. Just sharing info on bullet performance.

I have also done pretty extensive testing with the SSS through various other media. Penatration is its hallmark. Out of a short barrel they suffer. Out of my rifle they hit really hard at close range.
For use on game these bullets benefit greatly from a broad meplat. I like to very carefully remove the round nose. This lightens the weight just a tad and ups the velocity. It also causes a slight bit of expansion in some cases and helps limit penetration.
Overall a pretty neat round. I would prefer it in a bolt action. It wont cycle for me.

Jeez. There is no magic here. It's equivalent to a 5.56x45 55gr FMJ round at 700 yards or so. Or about like a 5.7x28 SS190 up close. It tumbles, creates a permanent cavity about as wide and long as it is, and that is that.
