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?

Jerry,
That powder has a "burn rate" that is too slow, for the 358-WSM.
Today, I was working with some 250 Hornady RN's (Not Regestered Nurses).
Having worked with a lot of loads and several 225's (Swift A-Frames. TSX, and Partitions), so, I had a clue as to where to start with my 250s.
I started load development in 2005 for my 358-WSM, and burned a lot of the slower powders such as 4350, 4831, and RL 15..., They are all too slow for optimum performance out of that cartridge.
I sent you some load data for the 225's that show them easily doing over 2900fps.
