A quick update. I have updated the details in my Gallery for my 260 Rem as it's now wearing a new True-Flite barrel fitted by Forum member Grant Taylor in Dundee. Shooting it's a bit tricky with a cracked rib, but the initial results are looking very promising. Using my old stalking load with no adjustments of any sort, I got the following results this afternoon.
All three legacy loads are shooting well in the new barrel.
