My goal with the .460 is an accurate 150 yard rifle with enough energy at 150yd to knock a deer down and keep it there. Southern Michigan hunting between farm fields and rural residential lots.
My 77/44 shoots ok but the .44 mag starts to piddle out at 100 yards. Sixty yd quartering shot at a doe last year was through and through and knocked her down, but a 100 yd rib cage shoot on a buck this fall only made one hole. He ran close to 80 yd but not in a straight line and fortunately stayed on my side of the creek. Moderate .460 loads and similar/heavier bullet weights should be moving along at 100 yds at the same speed as .44 mag muzzle velocity.
