In all tables: Lead is always in feet, wind drift and trajectory are always in inches, lead and wind drift are both at 90° angles. Wind
drift: A
45degree
wind
drift
angle isn't half the wind drift of a 90ºangle, but is
threequarters
the drift. It has a 75 percent effect, even though the angle is
only halfway between no drift effect and full drift effect. The drift
effect is not proportional, due to the aerodynamic ballistics of a
bullet in flight. Just remember that halfway between full and zero
effect is nearly threequarters the drift of 90degrees. Multiply
the 90º drift by .75 for 45º drift. Memorize
these aerodynamic
ballistic realities. Most
scopes
are One Quarter of an inch 1/4"or .25") per click
at 100yds scope, or (1/2" or .5") @200yds
Clicks Minutes of Angle (MOA) is 1/8" @ 50yds; 1/4"@100yds; 1/2"@200yds. Print small cheatsheets for each bullet weight, BC, & particular load, etc. Figure leads from heart/lung area on fox & coyotes. Coyotes and deer can run up to 40 mph. Use the length of the animal at longer ranges to determine the length of a foot and the lead. The 55 grain
bullet may be okay on
red and
gray
fox however, with a mere .133 sectional density it's a bit light for
coyotes.
Rick Jamison says an SD of .140 is the
minimum for coyotes, an a lower
limit of .210SD for deer! A 150gr
.308Cal,
SD is .225; 165gr has a .248SD. When it isn't
too windy I'm going to
use
this
55 grain bullet in my .243 Winchester with a 4 by 12X scope for fox and
coyote
hunting
and anything smaller. I need to get and try a 70gr bullet on coyotes, with
40.8grs of RL15, which is supposed to be a very accurate load.
I tried the 55gr nosler BT at 50yds on two inline milk jugs filled
with water. It blew the first one and the other one tight against it
cracked open and lot all the water from the shock of the first one. "Sectional
Density" is always the
same
irrespective
of bullet shape, here is a list of 6mm SD's: 55gr .133; 70gr .169;
75gr .181; 80gr
.194; 87gr .210; 90gr .218; 95gr .230; 100gr .242. Here's the
SD equation: SD
is the ratio of bullet weight to the square if the bullets diameter. The 6mm 55 grain Nosler bullet ( .133SD) has a higher BC than the 55 grain bullet .224 bullet which has a higher .157SD; 60gr is .171SD. Otherwise, it's my 243/06 wildcat on coyotes, with the 87 grain VMax bullet, SD .210, BC .400. This is still a better performing cartridge/bullet combination than the 220 Swift or 22250 combos. In my 243/06 Wildcat I tend to prefer the 87 grain Hornady VMax varmint bullets as they are better in the wind and hold their velocity and energy better than the lighter 55 grain bullets. The 55 grain Nosler bullets, in the past, have been accurate in my old 722 Remington bolt action rifle. The recoil calculator says: recoil velocity is 8.61 fps  recoil energy, 8.63 ft/lbs  using 50.5 grs. H414 powder, MV 3900 fps. That is mighty low recoil! With the 55 gr. bullet, and 44 grs. of H414 powder, the 220 Swift comes the closest in velocity at 3,833 fps  Recoil energy is 7.37 ft/lbs, recoil vel. is 7.95 fps, which is close to the 243 recoil figures. The range of bullet weights and total versatility allows the 243 Winchester to effectively cover the .224 or 22 centerfire cartridges! My late Uncle Viv Duncan loved the 220 Swift for shooting red fox, and could nail them on the run with regularity. Back in the 1960's he shot well over 100 red fox during some of those winters with it using a 40 grain bullet. 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 with a 300 yard zero. judging range on coyotes in varied terrain can be tricky stuff. These charts will 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, and that will get away if you don't drop him in his tracks. 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.

Red foxes were running targets par excel lance in the 1960's
