bore diameter…

Anyone know the bore diameter for the Discovery .22?
(I don’t have any ‘measuring devices’ the will measure that close.)

I have a Benjamin Discovery .22 cal air rifle.
What parts do I need to re-crown the barrel?
Thanks,

Response:
We have muzzle chamfering tools for this such as item 080-587-211. This tool set is designed to work on .22 cal rimfire rifles but may not be the best pilot size for your airgun. The bore diameters between the air rifles and rimfires are not the same and so the pilots do not always work. There are three pilot sizes for rimfire guns: .211, .213, .215. If you have any way to measure your bore diameter you can order the correct tool set or you can order the above tool set and see if/how well the pilot fits. The other pilots are 080-686-213 and 080-686-020 should you want the complete pilot set.
