Buff hunt sounds fun. I have a 45-70 trapdoor Springfield circa 1891 that was cut down (butchered) by someone in the far past. I cut it down further and mounted a tang sight (had to make a tang first).
Always wanted to shoot Buff with it. If you don’t mind me asking where is your hunt to take place?
Just so happens her Browning also wears a tang sight. We’ll be hunting in West Texas on a private ranch, it’s 140 sections. He started this herd in 1940 and has some huge Bull’s running around. My wife shoots the Browning very well but carrying it may be another story, she’s 5-2 an about 120 lbs. That rifle weighs 12 lbs, looks like I’ll also be a gun porter. The buffalo hang out in the northern end of the ranch where it’s allot more open, I’ll do good to get her within about 150 yards if we’re lucky. Getting in close enough for the bow will be even tougher. It’s a 60 lb Samick Bamboo Raider and I’ll be shooting 500 grain total weight arrows. If I can get inside 35 yards I’m pretty sure I can put one in the boiler room, at 40 yards I can keep 3 shots inside a 8 inch pie plate. Had to buy another freezer last year after she took two whitetail bucks and a 5x5 bull elk, if we just get one buff it looks like I’ll be getting another for the garage.
