The .454 Casull is one cartridge that Buffalo Bore Ammunition does not load to its full pressure limit. When loaded to its full pressure potential, the .454 Casull can become unreliable and unpleasant to shoot.
At upper-pressure levels, the following issues may occur:
- Heavy bullets tend to jump crimp, potentially tying up the cylinder (a serious problem in an emergency).
- Fired brass can stick in the chambers, making extraction difficult.
Buffalo Bore Ammunition believes that the following loads are extremely powerful, comfortable to shoot, and totally reliable:
- 360 gr. bullet at 1,425 fps
- 325 gr. bullet at 1,525 fps
At these performance levels, the bullets sacrifice nothing in killing effectiveness.
