Your firearm has been designed for ammunition of a specific type and caliber, do not alter the barrel, slide, or chamber of your gun. Use only ammunition specifically recommended by the manufacturer or your firearm. Never mix ammunition. Use only commercially manufactured ammunition. Never use a cartridge not specifically designed for use in your firearm.
Excessive pressure can damage or even blow up any firearm.
Ammunition with velocities and pressures higher than those for which the firearm was designed, will subject the firearm to additional stress and may cause excessive wear. If you hear an unusual sound or feel an unusual recoil when firing, stop firing, wait 10 seconds, unload the firearm, and examine the barrel bore for obstructions. Make sure your barrel is clear and free of obstruction. If you see an obstruction, have the firearm serviced by a qualified, licensed gunsmith. Never fire a firearm with an obstructed barrel.
