The article is wrong on one point. . 22LR can be shot in a. 22WMR gun. Not usually a good idea, with the marginally different diameters. But in a pinch, it will work. Of course, many revolvers have cylinders for both calibers. They are usually most accurate with only one caliber.
Yes, it can, I've done it. EVERY LR case splits in the mag cylinder, and NONE will hit paper at 25 yards.
It's a nice, concise, simple intro to the .22lr / .22wmr family of cartridges. I'd probably go for the .22lr in my geographic context; more folk have .22lr than .22wmr. My go to for long term self sufficiency would be a .22 Hornet...but that's a different story for a different thread.
Having a revolver that can fire both .22lr and .22WMR is a plus, and would probably be the only reason I'd stock up on WMR. I wouldn't bother buying a long arm just to fire that cartridge.
No, I would never do anything like that as it would be illegal. If I did I would probably make a fulminate of mercury, however I have heard that FFFF will make a suitable one as well if using fuse caps. It all depends on the brisnance needed to initiate the primary charge. To stay on topic, I always wanted a 10/22 in WMR for some reason.
I have found that lighter charges tend to be more accurate and greater charges tend to be less accurate. Olympic shooting .22 are low velocity rounds. The exception is 17 HMR I think that bullet design has something to do with it as well. Hollow points do not hold the pattern as good as pointed rounds. This is just my experience.
Forget FFFF BP as an initiator Powder, Not fast enough for initial Detonation.... MF is good, but would Degrade into CopperF fairly rapidly, and there goes the BallGame... PBAzide or PBStyphanate is the Real Deal....
