i love my savage 93xp cammo (.22 wmr) but i also love my mossberg 42m (.22 S L & LR ) for the price and the difference in power i think the .22 wmr is worth every penny i dont know about the .17 hmr cuz ive never fired one so i wont try to review, reccomend,or put it down.
ive done tests with the 22 lr and the wmr on various metals i got from work i work at an aerospace company so everything i get is ASTM approved(not junk)
a .070 piece of inconel on a 2by4 will stop a 22 lr round without really denting the metal much. now a 22lr will go through the same thickness of mild steel, (like the stuff a car door is made of). and stick in the 2by4.
now my wmr completely deystroyed the inconel and the 2by4 without remorse that is impressive.
to give you an idea a CNC machine (a computer controlled milling machine) has a tough time with inconel, it chews through the carbide bits. The metal doesnt really want to cut it is "sticky" it stretches and deforms if your not carefull. these machines tear through titanuim stainless and anything else you want. but not inconel.
the fact that a rimfire cartrige has the power to blow through it makes me an advocate for the .22 WMR i know a 243 or any rifle cartrige will to. but thats a whole different ballpark.
ill put pics up when i get my camera fixed.
oooh i just bought brownells "friction defense oil" its teflon and moly with all sorts of other goodies in it. i love this stuff i went to the range and put a few hundred rounds through it and the gun was warm not hot like it was when i used other stuff and for $5 for 2oz its a great deal buy this stuff you wont regret it i bought a 2 oz bottle and a4 oz bottle. delivered it was about $25
still a good deal
