Ok, so I just got my dad a lever action 45 colt for his b-day. I'm thinking I might plan a hunt for us at the beginning of the year and wanted to see what you guys thought about it's adequacy. Buffalo Bore lists there 260grn JHP heavy load at 1,450fps from a revolver, I've got to think coming out of a 20" rifle you'd push that to more like1,800 fps. Double Tap has one that is 255gn swc listed at 1,775 from a 16'5" barrell. For a 50-100yd shot, do you think a load such as this is enough to do the job?
