Question about 22's

First topic message reminder :

the first serious 22 I had 40 years ago was a Colt Ace.  It was ok, but I was into 45's, so no real experience.
Now, being old and having plenty of time, I am rebuilding my BE abilities, such as they are, to get serious
about it.  I have a 22 Ruger and a Marvel conversion. Both are really choosy about what you feed them-neither
likes Norma Tac 22's (probably because they are greasy), and both jam and stovepipe more than any 45 I
own, and that is probably six or more. The 22's are OK with Federal's range offering, but still jam.
I can see where a small skinny round is more difficult to feed than a fatter one, but it is likely I am doing
something wrong (I have done such before).  Wisdom much appreciated8)

Ok, it seems like wearing in the plastic mags helped a lot.  One of them still does not feed well, but the other 4 are good. Still not as
reliable as the GSG metal ones, but doable.
