It looks like to make a big advancement, and another choice of 22LR Ammo, We need a Tech at like CCI to make a smaller primer, and like the CCI Stinger with 1640 FPS has a better nickel plated case, I think it will be a little higher price than some of the 22LR Rimfire, I see that some of the good stuff is running around .20-.30 Cents a round, S&W should have no problem making something like a Model 617 22LR Revolver, just call it a 617-CF, CenterFire.. Just something to think about in these cold winter months..
