Those last two groups are great! I've been working with Re17, CCI BR-2, and 168gr TTSX in the 30-06 and the 300 Win mag with great results as well. Lots of velocity, good to great accuracy, and no signs of pressure. If you're going to push out to 500 yards you should look at switching to the TTSX because of its higher BC and better expansion at lower velocities the then TSX.
