Longwinters,
Just my thoughts on the subject, and clearly not everyone is in my camp on the subject.
I had a RUGER single six, my first handgun, bought about 1960 that had the interchangable cylinders.
I shot both the standard and the .22 mag ammo cause that is what I had.
However, probably about mid 60s I became a confirmed hand loader and started casting for the .357 that had replaced the single six.
This is where the .22mag REALLY lost about all of it's glammer/reason for being for me. I could reload and shoot a .38 load, using my own boolits, and a few grains of Bullseye for an extremely small outlay in $$$$$$$.
The .22 mag just became a ho hum cartridge that some folk bought but I didn't really understand why. Same goes, FOR ME, with the current crop of rimfire .17s.
OK, I know times have changed, but cost of those rounds is still a major issue for me, when balanced, with the abilities of almost any .22 or .17 centerfire round.
I use and enjoy a couple of .22s in the form of Mark II RUGERS, and a Clark Custom 77/22 for what they are, fun and very good shooting firearms and providing I'm not feeding them match/target ammo, reasonably inexpensive to shoot.
But for handgun shooting beyond that and for not a lot more, yes, I still make my own boolits, I can get a cartridge able to really get the job done if called on to do so. For rifle shooting, if my goal is to turn tiny ground critters onto a pink mist, well my 243 with a 55gr Nosler Balistic tip has it all over any rimfire, not even to mention the good sized list of great .22 centerfires.
So, all that to say this, the .22mag. has, FOR ME, always come down to a much to do about noth'in as well as being pricey for what I got.
No intention of casting stones at anyone who may use and enjoy the .22 mag or the .17 rimfires, but the above pretty much sums up the reason I don't lay out money in those directions.
Keep em coming!
