Jorgel, I’m sure this load and others on this page would work fine. However, you change up the scenario you are working toward a bit as opposed to a 375 with a good low-range scope. Having been around the big bears, I’d think you want to be well within 100 yds.
Think a very liberal bow-hunting scenario as to range.
And that’s after I see you put five into a tea saucer at 75 yds back at camp. Or at a hundred. With those irons. 😉
