When buying 22 Mag ammo, I have always bought cci mini mags in the past. {the exception being when my kids were little and learning how to shoot, with unlimited ammo, supplied by me}
I bought a several bricks of Speer Gold dot short barrel self defense 22 Mag ammo after they came out with it. {I like it for my 351pd} So after many years of firing the cci's {use them in my 9422M that I bought back in 1970 something} I would like to say that the reliability of rim-fire ammo seems to be more of a myth than fact. {and yet many just state it as a known by everyone fact}
I do realize that the **** bulk 22 lr we use to buy for next to nothing back in the 50's and 60's etc was **** and had dependability issues. I put that down to what we bought, not necessarily to the dependability of all rim-fire ammo.
There has also been dependability issues with center-fire ammo sourced from dubious companies for little or no money.
So, I'm just saying that this known to everyone fact should be re-evaluated . Cheap ammo is cheap ammo whether rim-fire or not. Duds go with that , not just because it's a rim-fire. {My 2 cents YMMV}
