22 LR self-loaders can be fussy, no doubt about it. IME the Ruger 10/22 and my own Ruger autopistols (I've had 3 of them) feed just about anything. They are very indulgent and forgiving.
Alas, not all rimfire systems are this obliging. Three of mine come to mind in this regard.
The first is my Winchester Model 290 rifle. My dad bought this as a trainer rifle for us kids in the mid-1960s with S&H Green Stamps. Simpler times, indeed. This rifle ran quite well on 1960s and 1970s ammo of any type--no balking, no sluggish feeding, no stoppages.
The family guns came my way after Dad passed in 1994. It was 1996 before I got a chance to take the 290 out for a shakedown cruise. I'm here to tell you--there was some real garbage ammo out there being sold by the Big Three ammomakers. It may have been affordable--and it may have been accurate--but it flat-out would not run in that Win 290. Nicely enough, my 10/22 consumed it happily. I grabbed some CCI Mini Mags and tried those in the 290--success! They ran like water in that rifle, and still do to this day.
Two Walther 22 LR pistols I had about this same time responded well to 'The Mini-Mag Ammo Upgrade'--a TPH and a PP. Those got flipped for large dollars. I appreciated the boon at that time, but I miss that PP something fierce. It was a nice little pistol.
In 2004 Marie wanted a sub-caliber trainer for her SIG P-228 9mm--she calls it 'Lucy' (short for Lucretia Borgia--Castilian Basque women can be spicy at times). We bought a SIG Mosquito pistol for that purpose. That stupid little pistol refused to run reliably, even on Mini-Mags at first. She Who Must Be Obeyed was not impressed--I was directed to sell this (expletives deleted) pistol in some very sharp Spanish. My beloved spouse can be a bit impetuous now and then, so I just told her "I'll see what can be done' and took it out shooting frequently. After putting about 400 Mimi-Mags through it, I noticed that its failure rate was lessening per magazine as the round count advanced. By about 1500 rounds downrange, the Mosquito was behaving itself exquisitely--and it still is. Marie had made peace with 'Lucita', and all is right with the world again. That pistol will ONLY run on Mini-Mags, Blazers, or SGBs by CCI, though. It is a real 'Steak & Lobster Cotillion Debutante'.
That is NOT complimentary--I like the Muddy Girls, I'm married to one and Marie is the best thing that ever happened to me. She will do to ride the river with, for damn sure.
Same story with CCI rimfire ammo--the stuff works. Yeah, it costs more--but aggravation is costly, too.
