Non temp sensitive pistol powder?

[willowbend]

Which of the new and older powders has the least amount of non temp sensitive to extreme temp ranges?I have shot Unique,Bullseye and Universal for years and looking to buy some new powder as i am about out and looking at getting around 900fps lead loads to 1400 fps hunting loads for the 357 magnum and was wondering what powders you have found that is not pushing high pressures and not having wild pressure spikes and losing performance during cold or hot weather temps.I was leading toward trying W231 and Alliant 2400 but some folks say it isnt that great for 38 special 110 grain loads.Here is what i will be loading as this may help.
38 special 110-125 jacketed for self defense
38 special 148 LSWC
357 110-158 JHP
357 148-158 LSWC

Look at H110 and W296 for the 357 Mag 158 gr JHP loads.
Can't help you on the 38 Special load.
