Have an old bonehill 303/12 bore cape gun, external hammers with non-bushed rebounding pins. 303 firing pin is in poor shape. What kind of tool is used to remove the pins? I will use this guns sparingly and with low pressure loads on both sides. Pins are same size shotgun and rifle side. Ideal would be to re-fit for bushed pins on 303, but gun was made 100 yrs ago as is. If I can get away w new pins made up in current configuration, will go that direction. No, I won't be doing any of this work myself, but like to do some disassembly within my limits to learn how gun put together. Thanks, Bob

Measured last night. It's hex shape .25. Maybe a thin wall socket in 1/4"?
