I experienced the exact same thing in my M700 25-06, 24" barrel. RL22 + 110 grain AB's gave great accuracy but sub-par velocity. Average was around 2900 fps. I recently decided to try Retumbo with the 110 AB. The result was 3/8" group @ 3244 fps. Very pleased with it so far. It did great work on a whitetail buck opening weekend here in Arkansas.

Don't speculate when you don't know, and don't second guess when you do.
