That's motoring pretty good with RL26, even with a 24" barrel. I get about 100fps less with H4350 and 130's in a 22" factory 700 barrel.
And regarding Hogwild's older post about the 100TTSX, I've been playing with them and Big Game. 47gr with R-P brass, CCI250 mag primers, and a 2.805" OAL yields 3,190fps in 85 degree weather. Nosler goes as high as 47.5gr for well over 3,200 with their 100gr bullets, so I'm trying 47.3gr this weekend, also because my groups were shrinking as my charge weights were going up.
couple months old, but if you are after velocity in the 260 with 100 grain TTSX,
try 43.5 grains of 4064.. Large Rifle primer...
3350 fps MV out of the 22 inch barrel of a Ruger 77...
faster out of a 26 inch barrel model 700 VLS...
