I use the 162's in my factory barreled A-Bolt 7-08 which I assume is a 1:9 twist but I've never measured. It likes them:
The only thing I don't like is some of the tips are on the bullets crooked. I had to roll each bullet on a table before loading, culling the worst wobblers. Two different boxes now. Oh well, they're cheap and the gun likes them.
I've also used the 208's in my 300. Nice bullets.
