Yes. If your gunsmith has a throating reamer in that caliber, he can give more free bore by removing some of the lands. I had this done to my 338 Win Mag. so I can seat the longer projectiles out much further, use a few more grains of powder and get higher velocities as the Model 70 magazine is nice and long once the spacer is removed. If the magazine doesn't allow you to seat the projectiles out further, throating can allow you to get higher velocities with slightly more powder, but sometimes accuracy may suffer as the projectiles are further from the lands.
