Jordan that is what I have seen with RL 26 also lots of difference in group size then the magic happens. Interesting both of our best loads were 67 gr in my 7 Rem Mag and your 7 WSM.
Ironically my buddy's load in his 7 WSM was RL-26 @ 67.5 and 3115 fps with the 175 eldx....works to a mile atleast. I wonder if 67 would be the magic number in his for 180s.
My 7 WSM ran 67 of R26 at 3075 fps with 5/8" groups. Dropping to 66 gr in once fired brass and I am at 3040fps average, sd's of 2.1-3.6 the last 3 times out and groups hovering in the .3's with several 5 rd groups doing better.
