Love me some 30-06....grin. With 1/10 twist I've had great results with bullets from the 110gr VMax on up to the 240gr SMK.
Although 1/10 has been the standard for the 30-06 for a good while, I don't think 1/9 would hurt anything especially with a steady diet of the heavy/long vld-type bullets.
I was reading where Bryan Litz has determined that a faster than standard twist had shown some BC enhancements in some of the vld-type bullets. I thought that was interesting.
