Here's the load data from the Barnes bullet site.
www.barnesbullets.com/wp-content/uploads/2007/02/30-06SpringfieldWeb1.pdf
It would be wise to follow Barnes' listed maximum of 50gr of IMR4064.

4064 -- why such a fast powder? With that bullet, and a 24" barrel, you'd probably get higher velocities and lower pressure if you used something a little slower, like RL-17, 4350, or H414.
Thanks for the input guy! Do these barnes bullets perform at high pressures than lets say an accubond or Hornady HPBT? Hodgdons data for 4064 and the Hornady 168 says that 50.8 gr will provide 2850 and 57,900 psi at max. Ive always used gilding metal/lead core HPBT's, if these TTSX's create 6000+ psi more pressure ill stick with the more conventional. I thought these provided less pressure, what an eye opener.

I've had excellent results with those same bullets in the x54R by backing off the max charge. They seem to do better that way.

in my 7mm the ttsx shot really well when i was close to compressed with a slower powder. i used reloader 19 and 22 at 64 and 65 grains.

I agree you will achieve better results with a slower powder like 4350. I use nothing but 4350 with 165gr or heavier bullets in the 30-06.
