Hand Lapping
Flitz also works very well, with half the amount of strokes
because it is more abrasive than JB Bore Paste. Use it the
same way.
It helped my 25-06 barrel, which was very rough, but did
little for my 209x50 barrel. It also has a couple of what I
would call "hour glass" patterns in the diameter of the
bore. Even at that it will shoot Hornady 180gr XTP's in
T/C Break-o-Way sabots with 150gr equiv loads at MOA.
But that's the ONLY bullet/load combo in which it will do
that. Want to do some LOOONG range shooting with PR
bullets, but they won't go less than 2 1/2" groups at 100
yards in this barrel. Got a 27" Douglas barrel from
Virgin Valley on the way............... :wink:
