Oddly enough over the years I have stumbled on two pre-64 270's with rusted bores, No three grooves though, one is now a 4 groove 338-06 in a Pacific Research stock, the other a 35 Whelen riding in a McWoody, I don't know what 'Ol Jess, does other than finding new clean steel to work with, but damn, both those rifles are shooters, I remain a highly satisfied customer.
