I am not sure, but the 215 was designed for the big Weatherbys. I would expect a lot more velocity than what you are getting.

    Here is a load posted on the reloaders nest. I don't know how much I trust these numbers, muzzle velocity looks too high?? Does anyone have any thoughts on this?

    Looks pretty fast, I would expect 3100 max from that barrel length

    Call Berger, Call Alliant, Call Hodgdon . In this day and age of cell phones with free long distance go to the source and get fast answers. I wouldn't trust that RL-25 load....3300 fps sounds way too hot.
