Leads are in
feet. Shooting at
running game
is much more dangerous. Be sure no other hunters are in the area and
that
there is a good backstop, and never shoot over a horizon under any
circumstances! A 100 yards is the usual limit for most hunters. These
larger caliber
bullets are even more dangerous to use on running game! The shot
must be safe, there are
very few good opportunities for running shots!
Speaking of
safe gun
handling, this should be taught to everyone that handles a shotgun or
rifle. For many reasons, you are much
more apt to have an accidental resulting
in shooting a person that is very near you in the field! Think about
these scenarios! Deer drives can
be very dangerous scenarios if not done following safety procedures! Wind drift: A 45-degree wind drift angle isn't half the wind-drift of a 90º-angle, but is three-quarters the drift. It has a 70 to 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 three-quarters the drift of 90-degrees. Memorize these aerodynamic ballistic realities.
This is a 150 grain bullet chart, the 7 mm ultra mag table uses a 140 grain bullet! In the 7 mm & 7 mm Remington Magnums the author of the, "Ultimate Deer Cartridge," recommends using the "120 grain Nosler Ballistic Tip bullets for deer." He says to stay away from the 120 grain Sierra PSP, it won't expand rapidly enough . I would use the 139 grain Hornady Interlock as it will break bones and still penetrate. Additionally, Hornady's new 139 grain 'Interlock' Super Shock Tip (SST) bullets might be just the ticket on deer. If you use Nosler BT 120 grain bullets for coyotes - point of impact would probably be around 1.7" high at 100 yards for a 250 yard zero. Remember you are figuring your lead from the heart/lung area! It is better to over lead than to under lead, miss clean or drop them in their tracks. Swing through the middle of the body, squeeze off your shot when the lead looks right and be sure to keep swinging, --follow through. Keep this lead information in your head and practice visualization leads in your own mind and with your rifle, squeezing the trigger and following through! It works for me and it will for you, too! Visualizing in your mind the various combination of shots and angles conditions your brain's reflex habits and will make a huge difference in your shooting abilities. I no longer claim to be a marksman as I have a lot of handicaps these days. The 7mm Remington
Magnum is quite a
cartridge and I can see why so many are influenced to buy and use it!
But for me, the 6mm's are just right for deer. I'm testing Hornady's
new 95 grain 'Interlock' Super
Shock Tip (SST) bullets in my .243 and 243/06 Wildcat on deer
this upcoming extended deer season. I've probably made
a lot of enemies posting
the
realities concerning leading running game, as I've heard every
imaginable story of how, "the
critter
was running at top speed 300 yards away broadside and I held on his
nose
and blew his brains out." "Oh yes, this ultra mag bullet gets there at
the speed of light." Well, if you were shooting the a 7mm Ultra
Mag
with a 140 grain Nosler Partition bullet @ 3425MV and the deer was
running
broadside at 30mph/44fps at 300-yards (no cross winds) bullet flight
time
is .296-sec X's 44-fps, you would have to lead his brain by 13' feet!
That's pure unchangeable ballistics math that can't
be
modified much by a mere miscalculation of what happened. At any rate
what
I put on the chart is very close to the required lead, barring a lot of
other
factors I won't list here; you can probably think of a number of them. SAFETY WARNING: At
any time when Hunters are too close together they
are in a high level unsafe hazard zone! If a deer is sighted one hunter
may move into the line of
fire of the other hunter. This is an imminent danger when a deer is
down
and then regains its feet and is escaping, either hunter when in the
process of shooting at a deer usually won't see the other hunter, --if
he is real close, --move into his line of fire. I know this from
experience
because many decades ago when I and my hunting buddy had downed a deer
and we were nearly upon it, it appeared done for but regained its feet
and began to run, I stepped forward and to the right to shoot it and
within
inches of having my head blown off when he shot the deer putting
it
down for good. I went down from the muzzle blast as we were very
close.
He was behind me and I assumed I would be the only one shooting! Never
assume
anything, or you or your hunting companion may end up dead! Take this
warning
to heart and always be aware of the imminent dangers of being close to
another
hunter or hunters! Whenever you are close together each must know
what the other is going to do, set some hard and fast rules and be
fully
aware of the other or others before firing any shot! Darrell Udelhoven http://www.udarrell.com/leadingrunninggamerifle.html http://www.udarrell.com/ultimate_deer_cartridge.htm http://www.udarrell.com/wisconsin_coyote_hunting.html A Page full of my
