Yes this was attained with RL26, 57.4 gr 3.484 COLSounds like 270WSM performance. That's good numbers from a .270 Win for sure. I'm guessing your powder is RL26 ??? Either way it's smoking the 170 EOL. Again, no surprise. Guys that know the .270s potential, know that it's very much a LR cartridge. Unfortunately many don't jump on that wagon simply because many many more bullets are available for the 6.5/7/30s to run data on and settle on the best one performance wise. Having really only one true heavy weight .270 bullet, it's tough to do much if your barrel doesn't shoot it well. There's no others to turn too. Hopefully that changes.
