the 22 tcm doesn't out perform it, not if you have the right ammo, I don't mean the exotic stuff that was meant for the government, and was stopped from Import, but the original white box, made in Belgium SS192-LF. it is getting hard to find and expensive though,,, Yes the current ammo is downloaded. but the original 192 will cause a crater in steel plate, while the Fed American Eagle, and the stuff with a ballistic tip, will only make a black mark on a painted steel plate, Sorry, has been so long since I fired any,,, May be the SS 195-LF I am referring to, it has a 28g alum core hollowpoint, and IIRC is apprx 2100 fps from the five seven pistol, it will crater a Bianchi cup style falling plate of mild steel . The newer 195 is like 1970 fps. Not sure what the Fed American Eagle fmj is. I agree with another post it is LOUD!!!!!!
