They are actually moving about 6000 mph faster than you are. Take a tip, lead the target.

I know, but you aren't going hit it anyway, so it hardly matters. They aren't much larger than that 6 foot bull the guy hit with the 45-70, but they are about 20,000 times farther away.

Make it 20 feet, instead of 6. At 22,000 miles that's about 0.00059 minutes of arc. Now if you can manage to make a round that can home in on the target, you're back in business, and you've got your own ASAT weapon.

but they are about 20,000 times farther away.

Make that 11,000 times, I thought the 45-70 shot was at 1 mile, rather than 2.
