Can't find a teaspoon of 26 anywhere in a 250 mile radius of home base. I do have some 25, which I know is similar to 26, just not as temperature sensitive. Is it close enough to use the 26 data with no problems? Close enough to reasonably expect the same results?
There's no RL25 data for the standard .270WCF listed in the latest manual at all. There is some for RL23, but at a quick glance it looks to be several grains down. The manual is a free PDF file. Best download it and see for yourself.
