Hottest 22 round

[Dirtlaw]

I'm trying to find something that will make my Mosquito cycle reliably. What packs the most punch?

[Oceanbob]

Federal Punch

Check out UTube.

[krypto99]

cci mini mags have worked for me.

[CSACANNONEER]

If mini mags don't work, get rid of it.

[Garv]

Try CCI Velocitor and CCI Stinger.

[chromatica]

+1 for CCI mini mags - must be the 40 grain version.

[44fred]

If I remember correctly, the word reliability and the Sig Mosquito never went together. Sad really.

Make sure you are holding firmly without limp-wristing.

[FeuerFrei]

I generally look for a 40 gr bullet rushing along at 1100 fps or better for a semi auto anything.

If it gags on that recipe I go to work on it. I really hate picky eaters.

I agree with this. Stingers are a nice option, but you shouldn't have to limit yourself to them.

[sealocan]

Another vote for CCI stingers. Yes, there expensive relative to other 22 ammo but you do get a nickel coated case for help with corrosion and possibly smoother extraction. They used to be The higher velocity 22 long rifle round and if I remember correctly that was the brand and type that was recommended by a few gun companies who had 22 semi autos that needed that extra recoil from the higher velocity round to help (hopefully) with slide function.

And if I remember they even have a mini hollow point that's designed with a rounded projectile tip so that should help with feeding.
Personally, I also like that it's made in America unlike some of the new Mexican Aguila high velocity stuff.

Lastly, as someone mentioned above it could be some issue/design defect from the factory the gun manufacturers seem to have when designing 22 semi-automatic handguns. I remember when one of walther's full size 22 semi-auto pistols we're having all sorts of problems that people were coming up with homemade fixes on YouTube and Walter might have eventually straightened it out I don't know.

Could be wrong, but I don't believe sig makes the mosquito any longer. There was a big issue with cycling. The stinger looks to be the best bet to see if I can achieve consistency. If not I may just give it away.

[sealocan]

And this is why I prefer revolvers for 22 long rifle caliber handguns. Sure you'll still get the occasional dud, that used to happen even more frequently when buying the cheap cheap bulk stuff when I was a kid a million years ago, but you can just pull the trigger again with no need to do a feed malfunction drill.
And if I were you I wouldn't give it away until I tried a few different things like stronger magazine springs, weaker slide springs made by someone reputable like Wolf springs, etc..

Or if you already have a centerfire caliber handgun with roughly the same design you can use this .22 pistol to practice your (guaranteed) failure to feed / eject and clearing the jam drills.

And don't forget to search YouTube for possible easier fixes. It's tougher now because YouTube has put more restrictions on Firearms videos but there still might be something there or one of the gun focused YouTube type video sharing sites like full30.com.

Sealocan,


We can always depend on you for great advice. Thanks. I will go with the options you have listed.

Lots of Fixes for lots of Mosquito issues... Not sure ammo is the fix

[gunnlover]

Finicky gun. Sold mine a long time ago. But I remember using mini-mags with great success.

[mattt]

22/250 joking ,you said fastest 22.

Best advice I’ve seen.

Yes I would dump it quick if it needs special ammo to work..I do not even own a .22 Handgun or Rifle that will not cycle on even CCI SV. I would not even a buy a unreliable .22 Let alone keep one around if I did..Anything that will not work with normal off the shelf ammo..Is unreliable in my opinion..Ammo is not going to fix that..

And I also do not buy substandard ammo either..CCI works in everything I shoot it in..

[jyo]

The SIG Mosquito 22 pistol was a dud! A family member bought one because it was a SIG---supposed to be good, right? Came with two recoil springs (neither worked)---was sent back to SIG and returned NOT WORKING and sent back again and returned NOT WORKING. SIG said try different ammo---I was managing a gun store at the time and secured EVERY brand and type of high velocity ammo and tried them ALL! NOTHING functioned 100% or even close... Last I heard, the gun was put on a shelf in a closet and may still be there... Not one of their better pistols...

[M76]

sig mosquitos bite

[JTROKS]

Check your barrel’s feed ramp, the ledge and condition of the chamber. At a minimum bevel the edges around the chamber and polish the chamber. If the feed ramp is rough get it polished - don’t remove metal from the feed ramp. Make sure that ledge is taken care of as in done properly. Putting a little deeper bevel at the 5, 6, 7 o’clock of the chamber’s edge should do the trick.

[GeorgeMG]

Aguila Interceptor?

[alpha_romeo_XV]

With 22LR and semi-autos, sometimes getting them to feed and eject is not just using higher velocity ammo but the shape of the bullet and lube on it which vary greatly from brand to brand.
Luckily I've stocked up over the years on many brands to test with. I found the Rem Thunderbolts work 99.9% in my gen.1 Walther P22 so I can save my minimags for rifles.

[AR22]

My further advice would be to get a Beretta..Problem solved..

[Beelzy]

CCI Stingers. Had a finicky Baby Browning and those were the only rounds with enough punch to cycle the pistol with total reliability.

[gunnlover]

I've never had a problem with my Browning 1911-22 compact. I've had it for 5-6yrs. Maybe I should actually take it out of the box and shoot it 😀. I've got too many guns in the box that literally have zero rounds thru them. Some years old.

[Jimi Jah]

I still have a couple of bricks of Aguila Supermaximum Hyper Velocity in solid and hollow point.

At 1750 fps, it's about as fast as a 30 grain 22 can fly.

However, it is not accurate. I get a 3 or 4 more moa out of my Henry Golden Boy, a 1 moa .22 rifle.

It does make a nice supersonic crack when you shoot them.

[SCMA-1]

The fastest 40 gr. 22LR is the Aguila Interceptor @ 1470 fps:

i thought it was 220 Swift. 4665 fps w/ 29gr bullet

[Ishooter]

If CCI mini mag doesn't fix the issue, then it's junk. No need to look further. Frequently shooting hottest ammo may potentially damage the gun.

[kkd]

A friend tinkered and tinkered ad nauseum before getting his Mosquito to work.
He used a Youtube video that was made by a gunsmith as his guide

Now it's reliable with MiniMags

Sage advice right here.

You are correct..I own a lot of .22 Handguns and Rifles..I do not have even one that will not reliably cycle even CCI Standard Velocitys..Now I have had a few in the past..Key word there is the past..If a Firearm is junk, just move on from it..Life is too short to deal with constant self inflicted aggravation,LOL

Mosquitos are notoriously finnicky about ammo. Sell it and get a buckmark.

[ACfixer]

We have a 'Skeeter, I've tried everything from the CCI Mini Mags of course that the manual says it needs, both springs, polishing the ramp, lubrication, different springs.... And some really hot CCI Stinger 1,600 FPS I think? And Aquila 1750 stuff.

That gun is a pile of jamming crap. I won't even sell it because I don't sell crap. It's good for jam clearing drills I guess, but the gun is a mutt.

Yep, I've had a Browning Buckmark for about 30 years, very accurate and very rarely has a hiccup.

[stormvet]

The thing to remember about the velocities posted on the boxes of 22 lr is that they are all recorded out of a rifle not a handgun. So all will be significantly less out of a handgun, but really no SA handgun should have a problem cycling anything with a listed 1100 or better.

[SharedShots]

Before doing anything else, first determine where the failure occurs. There are many individual parts to the cycling process so it's imperative to determine which one is affected.

If the slide isn't moving back far enough or too slow, putting attention on the feeding ramp (if there is on) isn't going to do much. On the other hand, if the slide does go back far enough and fast enough but then moves forward slowly, is it at the point it starts to feed or before that? A slide that binds as it moves forward won't be helped even if the feeding ramp is polished and properly angled.

A lot of guns are sold off or said to be this or that without those saying it understanding why the problems exist and thus they just use catch-all phrases like "It's a POS" or "It's junk".

It can pay huge dividends to examine why a pistol doesn't function properly and sometimes it's systemic, many of the same model have the same issue but it's easily remedied after which the pistol is as reliable as any other.

For certain pistols, how me the owner who says it's a POS only because the Internet said so and I'll show you a bargain that with little more than minor effort is the deal people ask "where did you find that?"

Many guns that are labeled as a "POS" or "Junk" aren't really that, it's the owner who says something like "if it doesn't work with X then it's junk".

The number of pistols called junk for no reason other than a burr on the slide or something not much more is amazing.
