invest arms hawken

I bought a Invest arms hawken 50 cal from the wifes grandpa. I was wondering if anybody knows the maximum powder charge the manufactuer recommends?..Thanks!!

My Lyman manual says 90 grains FFG and 70 grains FFFG.

In addition to the german gun proofing law you are allowed to load 8 gramm/123 grs of FFg bp into this rifle.
