RE: BARREL WEAR
I had a T/C Hawken in 45 cal.that was about 30 years old ,one year I missed a fine buck(looked to be an 8pt.)I went to the range and shot it and it started to fly all over the paper.I cleaned and shot it over and over.it was hard to keep it on a paper plate.some even missed it.
I took it to a gun smith and he said the barrel was ware out.
I callec T/C and told them.they said send it to them.they sent me a card and told me the rifleings were almost gone.they replaced it with a brand new one. the only old part was the ram rod.
they said it was rare to have one with that much ware.I would say I shot 1,000 rounds a year,some more , some less for 30 years.
so I guess they will weare out after a while,at least thats what T/C told me.
