Yes, "bullet sponges" are out there but not to the degree that cutting a BG in half is a requirement nor is carrying enough ammo on a daily basis for that purpose a good idea. At least, not if you carry enough gun to begin with. Now if you're in the Military and in a combat zone and all "they" are offering you is a .22 then carry as much as you can. Increasing the ammo numbers was the whole reason for adopting the M-16 to begin with and making them machine guns to boot pretty much says it all - NOT enough gun so "cut 'em in half" and let somebody else sort out the parts!

Yep, "Spray & Pray Generation" without a question.
