What does the gun weigh?

The accepted formula is that you need 6 pounds of gun weight for every ounce of shot in the cartridge.

If you match the load to the weight of the gun, it will be kinder to both you and the gun if you use that as a maximum shot weight.

Remember, less can be more and a lighter load may keep you on target if you are not being knocked cross-eyed by the recoil of too heavy a load.
