Thanks for the info Daryl....

This is getting interesting,and confusing even........

So,where can you buy this 'metaloy'? is it specifically for gun barrels? how would one go about using it??

Also,given that this means filling the old pits,wont the rust be breeding underneath the fills??? how do you get around this?

Is it possible to chrome plate the bores i wonder? memories of my Baikal 12g with chrome bores......great old gun. Totally rust proof bores.

Ben-Daryl, welcome back! you went hunting,wasnt it?
