Various .22 loads in different pistols

I spent some time yesterday, testing various .22LR loads from three different guns. The guns were new to me and I wanted to see what loads they each liked, so if I found what looked like a deal on .22 ammo somewhere, I'd know if it was worth buying. IE, if the guns don't like it, it almost doesn't matter how inexpensive it is.

The guns were a new Ruger 22/45 MkIII (the "NRA Lite" version with threaded barrel), a used Sig Mosquito, and a new Advantage Arms .22 conversion kit for glock 26. (Would have rather had a kit for glock 19, but apparently so does everyone; they seemingly can't be found.)

Tried 30 rounds each (they're all 10-shot pistols) of nine different loads, in each of the three guns; 810 rounds in all, and this is what I encountered. I was going to copy & paste the info, but the formatting gets horrifically dinked up, so I just took the lazy way; printed it out, took a pic with my phone, and saved the pic to photobucket.

The percentages are rounded off; 30 rounds is a weird number to work with percentages. Also, some of the terms in my notes may not mean anything to anyone but me... "FT-Strip" is just failure to strip a new round from the mag. Round fired, extracted & ejected the case, but didn't pick up a new one. Creates a cocked & locked gun, with an empty chamber. FT-Ext is failure to extract, creating a double-feed with a new round jamming up on the spent case in the chamber.

Excellent report, Thanks. I've had 100% with my AA on the G21 frame with Mini-Mag, Remington GB, and Blazer. Thunderbolt results were much the same as yours. Federal just is out as far as I'm concerned.

Yeah, Federal used to be one of my favorite mfrs; still is for a couple specific loads, but they don't seem to be what they used to.

Fwiw, OutdoorLimited has mini-mags on sale right now. Still not a great price, but 11 cents per round in a 500-pack:

To be fair, my Bersa .22's are pretty fussy with anything that's not high velocity, but when my Ruger MKII and SR22 started malfunctioning I knew it was the ammunition. I thought it was maybe a bad lot, but checking around it seems Federal Rimfire is just not up to operating a lot of semi-auto's.

I've read that the first Mosquito's were having a lot of problems. I don't know if they were fixed or not. I've had zero problems with my Glock 21 AA unit, but I've only shot the ammunition already named. Actually, a lot, maybe even the majority of .22 semi-auto handguns are ammo sensitive. My two BERSA's will fire Mini-Mags and Golden bullet's all day long, but start choking about once every other magazine on CCI standard velocity stuff.

I really don't know yet. The sig was used when I got it, and may need swapping to its other recoil spring. (They come with two, and I haven't experimented with the second one yet.) That's a part of the reason for testing - if nothing else, I was able to confirm that mini-mags run 100% in all three.

On the g26 AA unit; may be finicky partly from being new. Won't know until running it some more, but if nothing else it spurred me to order 4k of mini-mags to put back. One of these days I really want to get a G19 AA unit.

Well, in fairness to one of the guns I have to tell on myself a little...

I went out shooting again, this time with one of my sons, and the little Sig Mosquito locked back on empty for him every time; where it almost never locked back on empty for me. Turns out I was unconsciously putting my thumb on top of the slide-stop, holding it down and preventing it from locking back. Only gun I can recall ever having the slide stop there, where a 1911ís safety is. I consciously adjusted my grip, and it locks back for me 100% now as well. So it was my fault, not the gunís.

Still has some functional issues, mainly that it doesnít like the American Eagle stuff. But other than that, itís operating more reliably than it initially was. It was used when I got it, so itís not just a ďnew gun break-inĒ thing; may have been because it was so funky when put away by the previous owner, and the use is breaking loose some stuff that my initial cleaning didnít get completely out. Either way, really starting to like the gun. If I were going to carry just a .22 pistol in the woods, it might very well be this one, loaded with one of the loads it likes best. Since it doesnít have a 1911-style safety, I like the condition-two carry well enough, with the DA first shot in a pinch if necessary time-wise.
