Can someone explain to me why the 5.7 is all the rage and 22 TCM is almost unheard of?
I have experience with both cartridges and in MY OPINION the 22 TCM is equal to, or better than the 5.7 in all respects except, perhaps magazine capacity.
TCM No coating to worry about, one way or another. An acquaintance has one of those goofy looking FN P 90s and if the coating is gone, for all practical purposes, he doesn't even have a decent club.
TCM Cases can be made from readily available rifle brass if absolutely necessary. Some of you may not remember when the owners of the 5.7 would literally spend hours making sure they found EVERY fired case because the ammo was extremely hard to find.
TCM All things being equal, barrel length, bullet weight, etc. they are ballistically equal.
TCM In the case of the RIA, the 22 TCM magazines also are used for the 9MM which makes a caliber swap dirt simple.
I just can't see the infatuation with a cartridge that is as big a pain in the posterior to reload as the 5.7.
Now before anyone gets their panties all in a wad because I'm bad mouthing the 5.7, I want it understood I really don't give a rats patoot what one shoots. I have my favorites and you have yours. I just don't understand the infatuation with the 5.7 when, as far as I'm concerned, there is a better alternative.
