Probably good as any bore snake. My question is really about field cleaning in general. Why clean the bores in the field? Except in rare situations is there any compelling reason to clean the bores before you get back to the house/lodge/camper?
I will wipe off the exterior metal surfaces with an oily rag before casing the gun but I have never cleaned bores before getting back home, or to camp.
Just curious as to your motivation, Greg. I've never seen bores deteriorate before I got back to camp, or home.
Best, SRH
