The .22" Long Rifle rim-fire cartridge can be problematic in a box magazine fed auto because it is NOT RIMLESS - and it has another problem in that it is greasy externally lubricated due to it being a heeled or stepped bullet.
THAT Will Fill Your DOUBLE-STACKED MAGS Right To The Brim
Ah but" I hear you say ".. that unsupported rim won't be pinched or crushed properly by the firing pin" -
Genius ain't it - maybe?

P.S, I don't know why makers offer .22" round-nose solid bullets for Match or target shooting - when according to Wikipedia .. " In target shooting, they(hollow-point) are used for greater accuracy due to the larger meplat. Hollow point bullets are more accurate and predictable compared to pointed bullets which, despite having a higher ballistic coefficient (BC), are more sensitive to bullet harmonic characteristics and wind deflection."\

I really do believe in "if it aint broke, don't fix it". I have never had an issue with .22RF in a box magazine in over 60 years of shooting them.
ReplyDeleteThis is a solution looking for a problem.
I woulkd add to that that I have NEVER had a "rim jam" with a .303 either...... it's a myth.
DeleteHi Kathryn - I accept that you never experienced any issues with rimmed rounds .. but there are good reasons that RIMLESS cartridges were developed for semi-autos and I find it interesting that a analytic look at the old 'two-two' suggests that it's issues don't have to be ignored for ever as an unavoidable PART OF LIFE eh ... Cheers & thanks for taking an interest.
DeleteIf I were to go about a redesign of the 22, I think it would be cartridgeless. Allow a spark ignitor built in the bolt to set the round off. Features, no brass=cheaper round, No hammer to cock = less effort to cycle the arm, plus the trigger could be built to any pressure/style the shooter wants, Not shell = no transition issues for the bullet going into the rifling, no brass to eject, and higher cartridge count for a given size magazine. probably more issues would be fixed by dropping the cartridge.
