I have the same manual, and the speeds given are for a long test barrel. If my calculations are correct, the op can't get there safely with his chosen MV, barrel and bullet. However, it's his Ruger, and if he wants to overload it with 231 instead of using HS6 or something else slower than 231, I'll stand way over here and watch; not interested in an argument.
