Deer overlay drop charts

Interested to get people's thoughts on these two scale charts I did up today.

Like alot of people I don't have a scope with a ballistic turret that can adjusted for different range shots, and I don't have the money to buy one either. So I've been thinking of a way to more reliably allow for bullet drop when the ground doesn't allow me to get in close to a range there's not enough drop to worry about.

This idea comes from my days of Army marksman shooting, where we used scale drawings with our aim-off aim points for different ranges marked on the drawings.

Has anyone else tried something like this, was it successful?

Note: I have not used, tested, or validated these charts in anyway! Use at your own risk. I've used the DOC average shoulder height for Red Deer hinds (1m) and stags (1.2m) to base scale and 'ruler' measurements off. Aim points are a bit low, I need to fix them.

I use the same methodology for rabbits. A rabbit hunkered down flat is 4" from ground to top of shoulder, a rabbit laying at rest is 6", a .22LR sighted at 23m will be zero again around 70m and 10-12" low at 100m (dependent on ammo used). Therefore, at 100m you are holding two rabbit bodies high.

To make your picture even simpler, test and establish your trajectory, then overlay your holdover points based on range.

Going back too when I started. There wasn't dial uo scopes or range finders about. Think you're over complicating things. Graham Henry's rule of 3 for flat shooting guns , like 270 etc worked well. 3inches high at 100yds puts you about 3 inches low at 300. So center of chest to 300 and level with top of back at 400. Don't show day light though.
Although I'd say this is all pointless unless you have a range finder to know accurately the distance in the first place.

Aye and if there is time to range there is time to dial (can do it without having to look at the turret with practise).

What I do when hunting the same area is range a few deer 'hotspots' from various shooting points so you already know the range when you next see a deer there.

Since I found guessing the animal size difficult I took a different approach with my duplex reticle:
I worked out the sub-tensions on different powers.
At 8x with a 210m zero the top of the lower post was 350m. I could then divide the opening by eye for 210-350m.
Once I'm at the top of the lower post I zoom out. 7x is 365m, 6x is 390m, 5x is 420m.

I also had the opening sizes noted to make windage adjustments.

This allows you to make adjustments regardless of target size and shape.

This is the target used by NZDA for one of the postal shoots which may be useful

Interesting choice of 'X' location, I'd say it's probably the best aiming point if using MPBR.

Personally aim either one square higher or one up and left of the NZDA 'X'

Still much better than what is taught in the UK which is one square low and one sqaure right of the NZDA 'X' (approximately).

Took my first deer (red stag) with that shot and got very lucky it was quartering away slightly and it hit where I aimed...

Greetings,
The aiming point is not marked on the actual targets so the shooter can see it but a clear template is used for scoring. The X location has moved around the target with different versions over the years with one half a square loe and half a square right of that currently shown. Knowing where to aim at different ranges is not a whole lot of help if you don't know what the range is and for thoe who don't dial and seldom shoot past 300 metres, if that far, working out a range estimaing system using the scopes reticle could help. This is much more difficult with a SFP variable though.

Yeah, definitely plan on refining this into a specific chart for my gun and ammo, but the idea is this could be used for any bullet, together with a range finder and ballistic app.

Super useful thanks!

Inside 300yds, just point at centre of sholder,scope dailed 2.5 moa.Bang flop,no maths or charts required.Very colourfully charts tho for sizes of deer.

The concept is excellent, it's just a shame that 'Wilkinson' was only seven years old and had not actually seen a deer before drawing the target. What happened to the missing four thoracic vertebrae ?

There seem to be some missing in the neck as well. Probably due to squashing a deer onto a relatively small target. Does look plump and tasty though. Pity it is only 3mm thick.

Target isnt even square - 900 x 1000 WTF Wilkinson ???

Its a disney deer, very cute.

Some apps like Strelok have an option to display the points of impact on a deer or other animal target.

Disney was a sadistic barstool eh……………just look at all the kids that watched his movie’s and came away crying;):XD:

From your experience, was Wilkinson drawing a Hog / muntjac deer or one of those water deer and not a red ?

the hinds in hinds piss me off everytime I see them... all out of proportion... head n neck almost like a whitetail and that part of body is too small for the body....

Heres a 308 sighted for 200m using a plain duplex in a leupold VX-1 3-9x40 set at 4x.
The yellow circle is an example target zone. The very fine line in the middle of the yellow circle shows where the shot should hit at 100m. The shot will have fallen to the top of-the thick post at 326m.

Heres an example shooting at a rabbit with 22LR subsonic. The rifle is sighted in for 25m and the rabbit is at 100m. This is a mil dot reticle in a second focal plane scope (daft idea) but the dots are 10cm apart at 100m when its set at 10x magnification. The little cross hatches are half mil ie 5cm/100m at 10x. At different magnifications the reticle looks the same in your scope but covers different amounts of space on the target (subtensions) . The red numbers show the range in metres where the bullet is at the mildot (right) or half mil hash ( on the left). So, in this example, if you have the scope set to 10x you need to aim 2.6 mildots high.

I'm guessing this is the Strelok app you were talking about? I'll have to check it out.

Actually 1.3 m high by 1.0 m wide, The targets I have made are 1.2 m wide. In spite of not being scale correct it is a good shoot for those that might be alergic to round target shooting. The targets do take a bit of maintenance with only a few barnches shooting it these days. Taupo NZDA shot it twice this year.

+1 for stelok.
