I get it that propellant, muzzle velocity and pressure play into it. But I have to wonder if the chrome-lined barrels they use mitigate it?
Regardless, it just seems logical to me that this would be as good if not better than chrome/steel/lead fouling, and perhaps also engage with rifling easier too. Seems like plastic residue is easier to deal with, using less aggressive solvents than copper/lead.
And I think copper has better uses elsewhere. Worth a shot IMO...
