A collection of posts often on colt E- and I-frame revolvers: pythons, model 357s, officer model specials, etc. Topics not limited to: action jobs, fixing Bubba-gone-wrong gunsmith mistakes, and revolver porn. And sometimes I'll wander off the reservation and type random nouns and verbs that have nothing to do with our sole purpose, because who the hell can really pay attention that long?

22 jgr followup

I bought a very interesting officers model special that was converted to 22 jgr a while back. : http://coltpython.blogspot.com/2009/05/forensic-photos-weirdo-22jgr-oms.html


One of the most tricky things was that the gunsmith had modified the OMS from using a hammer mounted firing pin (as all E frames used) to having an internal one, much like the I frames that came after it (python, trooper, m357).


One of the less interesting things about it is that I didn't see a way to reload 22 jgr with any degree of happiness.

On friday however a kind soul mailed me a 22 WMR E frame cylinder so that I could convert the 22 jgr to 22 wmr. That was a major event.

Then I happened to stumble across a discussion about how 22wmr is .224 diameter and 22lr is .222 (or so) so conversions don't work. Since the OMS was converted from 22lr this induced stress: while I can install cylinders, I'm not setup to rebarrel .22lr to .22wmr especially on an essentially irreplacable gun.

But, lo and behold, today we discovered that 22jgr is .224 (as, apparently, most center fire 22's are):



So, everything is set for happiness at this point. Other than I have to fit the cylinder, which hopefully won't be a big deal.
