RCP, I have been having the same thoughts about a heavy barrel in a 8 twist.
To be able to run the heavier Bergers, JLK's, or just stabilize my 95 gr VLD's a bit better for LR.
Rifle shoots better than me already, so a re-barrel may have to wait until it starts showing signs of wear, or my pocketbook allows. Whichever comes first.
Nice work on the removal demo, thanks !
