In all tables: Lead is always in feet, wind drift and trajectory is always in inches. The .223 Remington is a little slow, but is very popular for varmints.

Figure leads from heart/lung area on coyotes. Coyotes and deer can run up to 40 mph. Use the length of the animal to determine the length of a foot. The 243's 55 gr. bullet has a MV of 4,000 fps and has a better B.C. than the 55 gr. 22 caliber bullet. The 243 with the 55 gr. Nosler BT will out shoot the 22-250 and 220 Swift with their best 55 grain bullets! The 243/06 will out perform all of them by a good margin!

The 55 grain Nosler ballistic tip bullet in the 243 doesn't hold up in the wind and its energy drops off rather fast. This is still a better cartridge bullet combination than the 220 Swift or 22-250, --print out and compare tables. I tend to prefer the 85 grain Sierra hpbt or 87 grain Hornady V-Max varmint bullets as they are better in the wind and hold their velocity and energy much better than the 55 grain bullet. The 55 grain Nosler bullets, in the past, have been accurate in my old 722 Remington bolt action 243 Winchester.

 I'm going to use the 250 yd zero for everything, it's too easy for me to misjudge the range and shoot over fox and coyotes.

I worked up these charts to give you a general idea of what it takes to gauge the speed, angle, and approximate lead required to make a killing shot on a coyote or on that once in a lifetime trophy buck that is headed for thick cover if you don't drop him before he gets there! You have to burn these figures in your mind using your imagination to visualize the required leads. That's why we need robotic type moving targets on rifle ranges that will aid in the repetitive practice that results in your brain automating leads for you, as in shot gunning.

There ought to be variable speed moving targets on every rifle and handgun shooting range. The target system should be movable to various ranges and run at various angles. Practice is essential to improve those shooting skills and to further determine each individuals range limits on running game. Remember that nearly everything that is shot, with a shotgun's shot pattern, is running or flying and those shooting skills vary a great deal between individuals due to numerous factors, with practice being a major one.

Start at the shorter ranges until you become proficient and move up, limiting yourself to reasonable shooting ranges. The faster the bullet over the range you are shooting the better!
