From top to bottom hairline, a three year old Texas white tail deer averages 14-16" in depth in the lung area, meaning from top hair line to bottom hair line. The "kill zone" including the heart, liver, and lungs is an area about 10" long by 7.5" wide. Shooting an animal in this area will most likely put it down quickly so that the shooter can find it rather easily. The very center of this area on a deer would put you about 5" from the top and bottom, and 3.75" left and right. In order to hit this area, the shooter must sight in their weapon to give them a window of rise and fall of no more than 3.75" to satisfy the center hold point of the kill zone. Not to mention you have to consider the wind.
.45-70 that is on at 125 yards .30-30 that is on at 125 has a drop
has a drop of almost 3.5" at 150 yards of almost 5" at 175 yards.
and more than a 10" drop at 175 yards.
A 10 mph crosswind affects a .45-70 and .30-30 bullet about 6" at 150 yards left or right, depending on the wind. Without a receiver peep that allows the shooter to simply click into the wind 8 clicks (each click = .5" at 100 yards) the shooter will have to hold off target in order to hit it. This is the main reason to have a good adjustable peep, which will allow you to easily return to zero after your shot is made by the simple twist of a knob. The same is true for elevation change, either up or down, with a return to zero.
A simple dope card with your rifle works very well. Remember, range finding is available with the DWBS front sight using the circular aperture.
Example: 14" fits just inside the aperture @ 100 yards
16" fills the aperture @ 100 yards
20" fills the aperture @ 125 yards
23" fills the aperture @ 175 yards
The DWBS receiver peep and front sight allows you to see more of the target with a crisp view of the aperture. At around 200 yards, 32" fits inside the aperture, so it is easy to place it on the top and bottom hairline of an elk. It just fits.
The vintage .45-70 has more energy at 500 yards than a .357 magnum has at the muzzle. Remember, John Wayne never used a scope! Using the complete DW Battlesight system on your carbine or rifle (front sight & rear receiver peep) should CUT YOUR GROUP IN HALF...OR BETTER!
I took a deer this year at 307 yards with a lever-action Model 95 Winchester, using a .220 grain bullet, round nose, with a velocity of 2000 fps. It shot straight through the animal above the heart. All of my kills this year (including deer and turkey) were shot from 175 yards to 300+ yards and I haven't missed one yet.
