That is the type of imformation I am looking for. Have you seen any velocity spread based on temperature change?R26 seems to really like the "short/fat" cases. I shoot it in my 338 Norma and I am getting 200fps more velocity over H1000 with the same pressure signs. I shoot a 300 grain bullet at 2970fps. This is the same with my 6.5 WSM, I am getting 200fps more than with H1000 & Magpro. I tried R26 in mt 280AI and 6.5-284 with no noticeable gain in seeds. I did get a little better speeds (+30-50fps) in my 300 Ultra with a 220 grain bullet over Retumbo.
Hope this helps.

I shot these in spring time and mid summer temps and did not see velocity spreads more than 15fps. I have not shot these in extreme cold to verify it.That is the type of imformation I am looking for. Have you seen any velocity spread based on temperature change?
