For one, I wouldnt be using a 30-06 at 30-40yds.
I like the SST's and we have excellent results with them in 30-06, 243, 270, and 280. We have had terrible results the times we tried Barnes and Nosler. We refuse to buy them, especially costing twice as much as other bullets.
It kind of funny around here. The store shelves are bare of everything. EXCEPT Barnes and Nosler bullets. You can find them in any store you go in. Apperently nobody else around likes them either.
