After trying several types of ammo for my S&W 1854, I found that these run flawlessly and are accurate enough for knocking down steel at 50 yds. I also like that they’re FMJ and significantly less smoky than the cowboy action rounds I accidentally bought. As always, TargetSports priced them low and shipped fast.
