1/4 to 1/3 of the (very accurate) shots from my H&R 732 Sidekick keyholed into paper. Fiocchi 97 Grain FMJ.
I'd suppose this is due to the sloooow muzzle velocity of this round from a 2" revolver? First time I've fired this one.
I was surprised at the accuracy at 7 yards, DA and SA. I understand that this is a very usual round for overseas target shooters.
