I am needing to fireform some 30-30 brass to 7-30 waters. I am still trying to develop some loads using W748. I have seen a recommendation to use a 75% load to fireform. Since I do not yet have a load, is 75% of the max load a reasonable place to start??
So for example, my TC contender manual (vol. 1) shows a 36.8 grain starting load and a 40.3 max load for a 100 gr. HP using W758. So is 30.2 gr. OK, or do I need to at least go to the starting load? This is for a contender in a 14" barrel.
Thanks in advance.
