This is an age old piece of chewing baccy. Do you or don't you. All of my rifle barrels are treated to a gentle run in procedure but I am still not sure what difference it makes. I'm old enough to remember when we would run a cars engine for a 1000 miles or such alternating the pressure a bit on the throttle. I have put a new V8 in my Land Rover and the engine builder insisted I take it easy, don't tow anything and keep alternating the engine revs up and down. That is what I did. Like all LR V8s it still likes oil, but goes like a bat out of ####(saved the computer the trouble). My Encore barrels had the gentle treatment and all of them shoot sub MOA, but probably would have done anyway. Three rounds, clean, three rounds, clean, three rounds, clean. Let it cool etc etc.
Way back 15 ...20yrs ago I remember a discussion at a party in Texas where the guys were talking about a system where barrels could be polished with ultra sonics of sorts. Is that still available in the US did it die the death? Did it work ? Sounded like a good idea for 17 cal barrels to ease copper fouling.
Slugging the barrel ...new one on me, explain please
Slugging the barrel---pushing a lead "slug" through the barrel to check gruve diameter. The surface of the slug will also tell the condition of the bore as to how the surface of the slug is.
TC barrels are one of the smoothest barrels out there. Shot many Harvey bullets in my 44 magnum with only a slight wisp of lead showing and all of that fell out with one pass of a brush.
Harvey bullet is a pure lead bulet with zinc washer fixed to the base.
Shot with a guy that had a TC hawkin in 50 cal. He could shoot all day without swabbing the bore, just pushed the ball down the barrel.
I do not see any need to fire bullets that have been rolled around in sand/dirt/abrasive. Want to ruin a good barrel, then do it, Midway carries replacement barrels, just so you know.
jag .... many thanks, never have come in contact with the term before. I do my very best to see my cartridges do not roll around on the floor in all of the crud. I agree with the old T/C barrels , the ones I have can shoot better than I can. Whether the stuff coming out of Springfield will be the same we have yet to see. No response to my question regarding the 'ultra sonic 'smoothing' of barrels, which was raising it's head back in the 90s. Any knowledge of that or did it just die a death?
