Are you sighted in for that 150+/- or do you use a BDC or hold over method. I would think being able to hit a orange trap bird at that distance, and animal would never stand a chance.
Looking at that bullet I wish someone would do ballistic gel out of a muzzleloader at say 100 yards and see what it does. I just have a feeling that that twisting Phillips head design is going to do a lot of damage.
