I am going to do load development in my 7mm RM using Barnes 145gn LXR and 150gn ABLR. I was quite impressed with low ES and speeds with RL16 in my 6.5 creedmoor and would like to give the RL powders a try in my 7mm. I want to use one of their newest temperature stable powders RL 23 or RL 26 because I hunt and shoot in temps from -25c to +25c. I have no desire to try anything other than temperature stable powders, the more temp stable the better. There seems to be limited load data on these powders so I`m looking for some info for a starting point for these two powders and some real life experiences and opinions with them.
