SBruce "I realize the difference between the 6 BR and .243 Win is quite a bit in powder capacity, but I would assume you could still get approx 3000 fps with the 85 grain bullets?? Should be enough for the bullet to do it's job. The Tipped TSX may be even better at the lower velocity of the BR." "QUOTE"
I don't get over 3000 fps with the 105 Bergers, but I read that other reloaders do get 3000 fps with the 105 gr. The BR gets real close to the .243 with better accuracy.
