Bill--Thanks for the comparison of the Lyman, Investarm & Cabelas max loads for their Hawkens. I assume that Investarm makes the three to the same standards. My Hawken is the Investarm, so far I have not exceeded the 80 grain max. for conicals. I only use Pyrodex in it. I do feel a little safer if I should stray a little over the 90 grains with a PRB. I doubt if I will ever use more then 80 grains with a conical, I shoot a 240 grain PA by Hornady. Thanks again.
