Hello everyone. I am trying to decide what type of powder to utilize in my Ruger M77 Hawkeye guide gun. The firearm shoots outstanding but has only a 20 inch barrel. Because Yogi said only I can prevent forest fires I am trying to keep this rifle from being as much of a fire breather and get some performance out of it as well. Here is what I have decided will be my main components so far for my upcoming black bear, wolf hunts with the need for some brown bear defense thrown in.

Hornady cases
Nosler 225 grain Accubond
CCI Primers

here is where I am stuck: I need to find a powder that will burn quick enough but also give me as much performance as possible. I have been looking at IMR 4831 / 4350 and RL 26. 4831 and 4350 has plenty of data but I just don't have any experience if it will burn enough powder up in 20 inches. RL26 I can not find much data on but was recommended to me by a friend at work. If you were to complete this firing solution what would you utilize as your powder? Thanks for the help in advance.
