Matt,
I don't have any real world data, just what I got off of Q.L. so take this for what its worth and be carefull.


93 grns of Retumbo under a 208 A-max with a 26' barrel in 85 degrees should net you 58200 psi at the chamber, yielding around 2885 fps. Your p-max is listed at 64977 psi

If you start testing with the bullet in the rifling back your starting charge off another three grains and work up watching for pressure signs.

Good luck and let us know how she shoots
