.22 conversion problems

So I purchased a new Kimber .22 conversion kit for my Springfield Mil Spec the other day, and today I got to try it out. I shot 200rds of Federal 40gr high velocity and 200rds of Winchester Wildcat.

With the Winchester, I experienced fair amount of failure to feed, failure to extract, and sometimes, I would fire, the slide would go into battery, but the hammer would fall on the half cock notch.

Problems seemed worse with the Federal. I had more failure to feed, failure to extract, a few stove pipes, and again, the hammer falling to half cock. And sometimes the extract wouldn't even catch the rim to extract the round.

But, there were exceptions. I did fire a couple of mags without a single problem with both brands of ammo.

My theory was that the heavier mainspring was not allowing the slide to come back enough to extract or chamber a round. But then again, I could go through a whole mag without issues. Another theory was that my thumb placement might have been slowing down the slide as I fired.

I don't want to jump to any conclusions, which is why I came here. Any thoughts as to the malfunctions? It was bad enough that a woman at the range asked me why I was having so many problems. I offered my theory, but it's just that, a theory.

But on the plus side; I've gotten pretty quick with the tap, rack, bang.

Yes. Both brands are 40 grains high velocity.

Try CCI Mini-mags (40 grain round nose). I have several 22 LR conversions and I've found the Mini-mags to be a good starting point. They're more consistent than the cheaper bulk stuff. As the conversion unit breaks in, try a quality standard velocity round like CCI SV.
