what if hornady decided to make a fmj 17 HMR?? I think its a S&W 617 or something like that, its a handgun thats shoots the 17 HMR. But hornady probably wont ever make the 17 hmr in a fmj so in other words its up to the ammunition manufactures wether the 5.7 is really a threat or not, aslong as they dont make fmj ammo for the 5.7 available. then noone has to worry about nothing. Again its all BS
