Speakin' of ammunition. Over the past few months, I've been out to Cabela's six times, looking for simple .45-70 Gov for my Browning High Wall 1885. None. Hard to find online and if you only want a couple of boxes, the shipping will kill you.
But, .22 rim fire. I have thousands of subsonic shorts. Lord knows how many standard velocity .22 LR. I have thousands of rounds of .223 Remington, around 600 rounds of 556 Nato (the .223 is for a Remington 700) and I got the 5.56 mm, when I finally went out and picked up one of those Scary Black Guns, which I have yet to shoot.
On the .22 rimfire, I've always been drawn to the unusual. I went and picked up a new Browning SA-22. It's a Japanese made one. But, the old Belgian that I've had since I was a mean widdo kid looked so lonely, so I wanted to introduce him to a new Japanese bride (figured if one of them was good enough for me, it should be for him as well). While I was there, waiting for the answer on the 4473, I walked down the cases of side arms. I'm not much of a handgun guy, I have the wheel guns that I like and one semi-auto (Springfield XDM 4.5 in .45 ACP).... but there in one of the cases was a display of North American Arms .22 revolvers. I was shocked as to how small they were, so I had to have one. Until you leave the store, they can always add it to the form. On sale for $199.00 and the cutest little thing you've ever seen, If you drop it in a shirt pocket you can barely feel it. I have a Bond Arms Rough Neck and it dwarfs this little .22 ... Makes the derringer almost look like a heavy-weight giant.
.22 LR and a little 1 3/8 inch barrel and from what playing around on a can of beans, I do believe that it would do the job.
.22 rimfires are neat little rounds. From boyhood to old man.
