Very informative post about 22LR fussiness

re: 12/15 Martini: I had one of those fine single shots and loved it. Somehow a buddy talked me out of it....slicked it up just a tinsy bit and claim 1/4 MOA in his precision bench rest matches....freaking out his multi$$$ modern bolt-action friends.

Cleaning:
I've found it works best for my hand guns to brush out the chamber now & then and at least chip the hard crust off the extractor/firing pin area.

My early enthusiasm for a 617 was suddenly jolted into a different gear, when trouble arose in closing the cylinder. Bit by bit it got harder & then imossible to close the crane.

Not only professing befuddlement but demonstrating shear ig'nance......I was shocked, shocked I tell you....to discover that after only a mere 3 or 5000 rounds unbeknownst to the clueless operator.....that crud/debris/hard crusty stuff had accumulate so heavily an actual accretion horn had developed, like a heel spur, on the crane rod/frame junction.

[Sound of one hand smacking forehead]...DUMMY!

Yes, all issues resolved including difficult loading etc.
What it was, was the exuberance of actually having run thru an extraordinary stash of 22LR fodder without stopping to clean.

The bore on the other hand, appears...well....boring.....no debris visualized.

I've heard of this mythical 22 long rifle ammunition of which you speak, but it's been many moons since I've seen any in the wild.

However, Iomegan is not a myth. He exists.

I also ran into difficulties to close the cylinder.
But it happened overnight.
Trying to narrow it down, I took the cylinder off the handgun and off the crane and placed it manually where it should go. Positioned this way, it would fire (I mean pull the trigger on snap-caps) twice and was unable to even cock the hammer for a third shot.

I sent it off to one of two S&W recognized warranty/repair centres in Canada. Still waiting to hear back from them.

I have always gathered what ever stock of 22LR I had on hand, my sand bags & bench tested every new gun I acquired. This very thought provoking discussion of 22LR ammunition may not be definitive but is a good place to start.
Yes, 22LR is one of the last hold overs for what was once he common "external lubricated" bullet types. It is wise to remember this.
I was lead to this post while investigating feed issues on a 22 cal pocket semi-auto. It had been a while since I dealt with this but I am going to change my policy. I am going to only use washed bullets in my semi-autos... I'll continue to accuracy test from the bench.
