The traditional patched round ball slows down like a ping-pong ball in flight.

From Lyman's Black Powder Handbook:

.495 roundball, ballistic coefficient .070

muzzle velocity = 1700 fps.
25 yards = 1470
50 yards = 1273
75 yards = 1102
100 yards = 995
200 yards = 734

five mph crosswind drift
25 yards = .30"
50 yards = 1.24"
75 yards = 2.95"
100 yards = 5.39"
200 yards= 21.2"

These bullets slow down and drift like balloons in crosswinds. Just like with bowhunting, hunting with a traditional muzzleloader is all about dealing with the limits of your equipment.
