20 grains of H110/296 with the 250 LBT is max...it sits the base of the bullet right on top of the powder charge. Velocity from a FA 97 4.25" barrel is 1309 fps...it is somewhat "snappy".
Federal uses this same bullet in their CastCore load. It is only going 1080 fps from a 4" S&W 57...it is much more pleasant to shoot and I doubt any less effective.
If you want an effective bear bullet for the 10mm get some of the Montana 200 grain LBTs...they have fed in the 1911s and Glocks I have shot them in.
