Many years ago I was looking for a good timber anchoriing round for my friend's 308win. The thought of a 170gr FP at 2600FPS held great promise so I called Speer and asked someone in the ballistic lab about using it for the 308. He told me there would be no problem using the 170 at 308 velocities. He said it would open up more violently, but would not blow up and would kill very nicely.
So, on his advice, I loaded 4064 under the 170FP and gave them to my friend. He proceeded to kill almost 20 deer over the years with that load and NEVER needed a second shot. Deer dropped so fast it was like flipping a switch. Running, walking, standing, it didn't matter. That big FP hitting at 2600FPS was like ther Hammer of Thor and shot flat enough for 300yd shots if needed.
When I started loading for my 308 carbine, I worked up a load with 170gr FP and plan on using them this fall too. Your 30'06 should be no different. Use 307Win data or loads for 180gr bullets and you should be fine.
