I have a few Antique revolvers that can push a 250 gr .454 dia keith bullet 1200 FPS but thats with a load of 2400 powder, but them are my Special custom solid framed guns

.
Most 240 to 250 Gr bullets doing 700 to 800 FPS is gona do the deed up close on a black or a cougar wolf ect, id figger.
my Antique 44 Russian and or 44 SP SAA colt shoots about 850 FPS which is a comfortable accurate load.
Remember the reason you have and antique revolver on your hip any place its legal to Discharge a None Restricted firearm is for target shooting.
Thats what your reason must be or they will try and say you are useing it for hunting.
You cant hunt in B.C with a handgun even and Antique one.
But you can and should target shoot in remoat loctations

Shooting at cans or paper or Cactus or other drought resistant plants ect is AOK.
