If oil and heat make tar, like T/C suggests in their propaganda on BB, then our centerfire rifles must really be tarred up by now.
When I first started this ML thing I was to told by the old guys shooting traditional guns.... --> Oil - heat - pressure and real black powder does make a black tar like substance in the bore.
I think I can say I happened it to me once - when I first started shooting @ a Rhondy event - I bought some GOEX and by the 4th target on the walking trail my bore was so gummed I could get anything down. My group was very helpful getting meshooting again - but I could see the smiles on their faces...
