I am going to NW Colo. in the 3rd rifle season with OTC tags @$480 Nov 5-11.
I once shot a cow elk around 550# with my 45 Colt Ruger BH pistol using these 300 gr Hornady XTP Mag HP bullets at about 75 yds thru the lungs it was a pass thru shot and she went 100 yds before she dropped. That was at 1600fps out of that pistol, so I'm guessing 100 gr of 777 out of a 28' barrel should do the job out to 150 yds or so. WB
