Marstar Canada: Unsafe Arms and Ammunition Combinations

Ammunition used in a firearm must be the same caliber or gauge as that marked on the firearm by its manufacturer.
If the firearm is not marked as to the caliber or gauge,
or if it appears that the original marking has been overprinted or changed,
it is the responsibility of the gun user to have qualified person determine what cartridge or shell can be safely used I the firearm.

The firing of a cartridge or shell other than that for which the firearm is chambered can result in the cartridge
or shell rupturing and releasing high pressure gas that can damage or destroy the firearm and kill or seriously injure the shooter and persons nearby.

There are countless combinations of specific cartridges and firearms which are unsafe.
Many of these unsafe combinations are recognizable because of specific dimension differences between the similar chamber and cartridge dimensions.
It is not possible to list every unsafe combination; therefore, in the interest of safety, use only the cartridge
(or shell) designed by the firearm or ammunition manufacturer for use in a specific firearm.
The cartridge caliber or shotgun gauge must be marked on the firearm frame, receiver or barrel by its manufacturer.

The practice of rechambering firearms is not guided by industry standards.
It is possible that a firearm which has been rechambered may not be rechambered properly or the rechambered caliber may not be marked on the firearm.
The firearm user is responsible to find out from a qualified person the cartridge caliber or shell gauge for which the firearm has been rechambered.
