Looking at the old survival rifle, for those much more skilled than I, how far up can you take the bolt lock system before you have to have locking lugs. That just milled a slot in the shroud rather than milling lugs for locking. That would solve about 90 % of the problems of building your own bolt action. Mauser actions take some tricks or some expensive tooling to make locking lugs in action.
Actually, the Mauser is a pretty simple design to build. The trick part is cutting the receiver lugs using a fly cutter, then the bolt lugs can be measured and hand fit pretty easy! Fitting the Claw is the harder part! A more simple design like a Remmy 700 series eliminates the claw and and simplifies the entire system, though you loose the secure feeding that makes the Mauser the superior design it is! Most Bolt actions are are pretty easy to design and build, and using the bolt handle as the locking lug has been standard since the small .22 cal chamberings have been with us. I would say any thing bigger then .22 mag should have bolt lugs! Most bolt actions can be made on a lathe with basic tooling!
there are several reports that some types of .22 WMR / .22 Mag ammo are notoriously unreliable some of the reports state [ the ammo ] "failed to feed reliably with jams occurring about every 8 to 10 rounds"
If you must have a rimfire then here is an option, but in 22LR. Mossberg Rifle Blaze .22lr Kryptek Highlander 16.5" 25rd 37319
17hmr is good. During the ammo shortage no one wanted it. It was the only plentiful rimfire. Me and my wife both have matching marlin bolt action 22 mag rifles we both bought about 20 years ago long before we knew each other. I'm trying to find a gun smith to add 1/2x28 threads to the muzzel of mine. I already have too many 22lr guns. If I wanted something to turn small game into meat spray, advertise to everyone for a few miles I'm shooting and get the cops called on me I would use 223.
One word, Suppressor! Not trying to poke holes in your post, but loaded for subsonic it doesn't spray and still hits hard enough to make the others a question mark in performance! Out side of that, the .22 Mag is pretty darn loud!
If I wanted silent, I'd use a pellet rifle. Plenty of those on the market today --powerful, too. And best of all, it's not a firearm according to BATF.
I got my dad's old gamo 25 cal pneumatic spring pellet gun, ballisticly it's about a 22CB short. It lobs a 40gr bullet at about 550fps. But is is louder than a 22LR locking action rifle shooting a 22CB short.
I now have gemtech a GM22. It's robust monolithic design is rated for 22wmr from a rifle. I'm not ever putting that GM22 on the end of a 223 with subsonics. Because if I accidentally fire a full power round though it, no more gemtech.
Tested: Kel-Tec CMR-30 .22 Magnum Rifle YMMV they apparently tested an earlier version of the unit while it was in limited production
I can tell this post pissed some one off. Expect to see lots more 22wmr postings is all I can say, every possible bit of 22wmr news I can find will become it's own post.
CZ, Savage, and Magnum research currently offer .22WMR semi autos, if that is worth anything. A lot of people dislike the Keltec for the same reason they dislike the PMR 30, not shooting specified high velocity ammo, so it jams, and they hateit. Know a handful of guys who run them, and they all agree they are keepers. The savage (A22 Magnum) looks like a solid buy, and the CZ is a sexy beast, but it is a CZ, so...
I know it wasn't you. I love you sec monkey lol. A couple of things I noticed about this 22mag post really got under some ones skin, so of course I'm going to irritate them further as much as I possibly can.
I have the A17 and reliability just isn't that great. The A17 appears to be dirt sensitive worse than a first gen AR15 and is sensitive to the viscosity of the oil being used on the bolt carrier being too thick. The aluminum feed lip magazines appear to wear out by around 1,000 and definitely after 2,000 rounds or so.
