WC-735 Spherical – 5% faster than H-335
I would assume one would start with a lower than H-335 load for the calibre you want and work up. Some others here I'm sure have used it, and I did see info on other forums from a google search.

I drop all loads 10% from H335 when working up. It makes working up a load a little longer since I wind up making very anemic loads at the start and it usually does not matter since I wind up within 5% of the max listed for H335 before I really start getting what I want and usually at the max before I stop, but there are no signs of pressure problems since listed max's are not really the max in most cases but just the legal max.
THAT BEING SAID, START LOW AND WORK UP ON .5gn INTERVALS UNTIL YOU GET WHERE YOU WANT TO BE!!
It is worth an additional 25 cases loaded and fired to make sure you are safe.
edit: although I have not loaded 150gn in my rifle, I have loaded 165gn with 40.5gn of WC735 with excellent results. 2600fps and that is, again, within 5% of H335 posted max data. No bolt sticking, but groups began to open up after that.
