Thanks. I've already been looking at .358 Norma loads. The .35 WSM has about 95% of the case capacity of the Norma, so I plan to reduce Norma start and max loads by 5%. However, I've not yet seen any .358 Norma loads using RL17, which is what I want to try next. Since RL17 and IMR4350 are alleged to have very similar burn rates, I've loaded up a series using RL17 and the 250 Speer Hotcor, starting at 63 grains and going up in 1 grain increments to 68 grains.
Any opinions anyone, before I go to the range next week?
