Trystan thanks for the info. My R26 loads were too hot at over 90 degrees but they may have been too hot at any temperature. I am going to try your R17 load with R16 as it is supposed to be more temperature stable and loads really close to R17. The 129-130 grain bullets have been a staple for my 6.5x55 and the BT kill really well, but so do the Hornaday's and all the others.
I'm down to my last bit of R17 and purposely haven't bought more. I'd be interested in finding out how well R16 works for you as I'm considering that as well for 130s.
