But a Partition might drift 3" more at 500 yards!
Or a foot more, depending on how hard the wind is blowing
Most guys shouldn't be shooting if the wind is blowing that hard, but let's think of it this way- if 450-500 yards is the max distance, and we assume that our wind call could be less than perfect so we limit the acceptable wind drift to let's say 6", a slippery bullet will give us a margin of error that allows us to make the shot with zero compensation in a 7-8 mph or less full-value wind, where a less aerodynamic bullet may exceed 6" of drift with anything over 3-4 mph of wind. So a slippery bullet may allow us to shoot in stronger winds than a bullet shaped like a brick, without exceeding our allowable wind drift. Just something to consider in this whole discussion of bullet selection
As far as construction is concerned, it doesn't take much bullet to kill a sheep. After sending a few bullets through a couple of different BH sheep, I've never seen one keep a bullet inside, and we're talking bullets ranging from Sierra MK's to Barnes X bullets, and shot angles from broadside to hard quartering.
