Re-Barreling a Shilo

[DirtySteve]

I have a Shilo 45-70 with a 1-18 twist. I used a teslong bore scope and the barrel looked like 45 miles of bad road. Chatter marks and inclusions in the bore. It seemed to shoot fine, however I don't think a rifle costing as much as a Shilo does should have a poor looking barrel on it. Plus I want to experiment with a faster twist rate.

So today I ordered a Douglas premium barrel in 1-16 twist. The big question is who should I get to rebarrel the rifle? Shilo, C Sharps or someone else?

On a side note I am not married to the 45-70. Should I do a 2 & 4/10's 2 & 6/10's? It will be for shooting out to 1200 yards.

Thanks for any in put..
