MM - The side of the barrel is stamped 6mm Rem and you are correct as that is when Remington made the twist change to try and keep up with the 243 but when I ran a cleaning rod through it with a patch, it measured one full turn in 12 inches.
I did just call Remington and gave them the sieral number and she said that is should have a 1 in 9.125 twist rate barrel on it as no 6mm Rem, except for the BR model, came in a 1 in 12 barrell. So now I'm back to square one on why this wont shoot 100 grain bullet.
