It is a standard 600mm 22cal with a slug liner now. I have a pellet liner thats the same lenght I would like to put together as a kit for now. Future I will possibly want to change it to a 25cal slugger 600mm and or a 500mm 22cal pellet setup.
Slug to pellet liner for now. Will eventually be looking at caliber as well. I have a liner just held off on the full kit because I didn't know how much I would be swapping back and forth. Do you have a list of the parts needed?
