I just spoke with Bob. What a truly delightful person. He has been handmaking bullets since 1954. Says he is not getting rich, but does just because he enjoys it.
For what it's worth, for the 7mm WSM
I am having built with 1 in 9, he recommended his 156 gr. rather than his 176. He thought the 1 in 9 was borderline and that heavier bullets would require 1 in 8 at least in the 7mm WSM velocities.
