Load data question WSM's

[feelinducky]

I have 2 rifles that I need to work up some new loads for. I'm hoping someone can give me a little advise on minimum and max loads.
#1 270 WSM 145g Sledge Hammer using RL 23, RL26 or IMR4451

#2 300wsm 181g Sledge Hammer using RL 23, RL 26 or IMR 4451

Thanks in advance.
