In reality, a 6.5-06, or 6.5-06AI will get incredibly close to the same velocities with handloads. A 6.5-284 will get close. All of those will burn 2/3rds the powder and have 2-4X the barrel life.
I’ve hit 3400fps with 130’s and 3300fps with 140’s from a 6.5-257AI, but it was hard on brass. With Lapua brass it would probably be manageable without loosening primer pockets, but I couldn’t find any 8x57 Lapua to form it from at the time. My current loads achieve 3250fps with 130’s, 3150fps with 140’s and 2975fps with 156’s. The 156’s could be sped up a bit if I would spend the time and components to experiment with a longer seating depth and different powder.
If you want that cartridge, by all means keep it. Sometime we want what we want, and that’s just it. If you want a hot rod, but aren’t sold on the 6.5-300Wby, there are better ways to get equal or near equal performance. If you don’t need a hot rod, there are a million other cartridges out there that are far more practical.
