Print Handy “Cheat Sheet” Ballistics Drop Chart for Your Rifle

Hornady Ballistics Calculator

Hornady Ballistics CalculatorNeed a simple, easy-to-use drop chart for your rifle? Something you can tape right to the buttstock? Then check out Hornady’s handy Online Ballistics Calculator. This user-friendly calculator will compute your drops accurately, and output a handy “Cheat Sheet” you can print and attach to your rifle.

Here’s how it works. From the Ballistics Calculator Page, first select 4DOF or Standard. Then simply input G1 or G7 BC values, muzzle velocity, bullet weight, zero range, and a few other variables.

Click “Calculate” to view the full chart (shown below). Then click “View Cheatsheet” and the simpler, 4-line Drop Chart (shown above) appears. Click “Print” and you’re done!

The online ballistics caculator is easy to use. You can select the basic version, or an advanced version with more data fields for environmental variables (altitude, temperature, air pressure, and humidity). You can also get wind drift numbers by inputing wind speed and wind angle.

Conveniently, on the trajectory output, come-ups are listed in both MOA and Mils — so this will work with either MOA clicks or Mil-based clicks. There are more sophisticated ballistics solvers available on the web (such as the outstanding Applied Ballistics Online Calculator), but the Hornady Calculator is very simple and easy to use. If you just want a basic drop chart, you may want to check this out.

A Day at the ‘Dasher Dome’ with Birdog and Voldoc

Report by Birdog
Forum member John S. aka “Voldoc”, came over Sunday to check the elevation come-ups on his new March scope. At my home range, dubbed the ‘Dasher Dome’, we had either a gong or paper target at 100-yard intervals to 800 yards. Voldoc wanted to check his ballistic chart against real world conditions. Voldoc will use this test to verify his come-ups for a “quick-view” BDC tape that will be applied to his elevation turret. He was running his “go to”, tried and true “red mist load”, an 87gr Hornady V-Max. The rifle was a Nesika-action 6mm Dasher with 1:12″-twist HV-contour Krieger. Doc has doubles with this combination out to 700 yards and many kills past 1,000. [Editor’s Note: We featured Voldoc’s varmint rifles in our Tennessee Triple Threat story, a Gun of the Week article on this site. Notably, Voldoc made a 1,000-yard plus prarie dog kill with a 20BR shooting 55gr Bergers.]

Dasher Dome Voldoc

My ‘Dasher Dome’ is a good place for testing. Dirt berms have just been completed at 100, 300, 600, 700, an 780 yards. Voldoc started at 100 and shot at 100-yard intervals recording his elevation at each interval. His ballistic chart was within a click or two at each distance. When he reached 780 yards, he repeated the test at each distance down to 300 yards. Dead on!

BDC Turret Tape XterminatorCustom BDC Turret Tapes
Doc already has ballistics tapes fitted to his Nightforce-equipped rigs. But Doc’s new Dasher has a March so he need to confirm the come-ups. The tapes, made by Forum member Dominic (aka “Xterminator”), show rotation clicks for various yardages. There are versions for both standard and “High-Speed” Nightforce turrets, as well as some other scope brands. For more info, send email to: media-banc [at] videotron.ca . Learn more about Dominic’s custom come-up tapes in this Forum Thread.

Confirmed results at 780 yards
Sub-Quarter MOA group on Steel Prairie Dog

The photo at right confirms that VolDoc has his zeroes confirmed at 780 yards. Look closely. That’s about a 1.5″ center-mass group on ‘Chico’ the prairie dog (lower right). Nice Shooting Doc! Chico’s buddy, ‘Chuckie’ the steel ground-hog, took many hits. Show in photo are three hits in the throat zone.

Good Friends, Good Rifles Make for the Best of Times
Birdog reports: “Overall, this was a great way to spent a Sunday. Temps reached 103° F, but Doc got to the ‘Dasher Dome’ at 5:30 a.m. and we beat the heat. After testing was completed, we walked two miles with temps in the 90s. What can I say — good friends, good BRs — this was the best of times!

Serious Rangefinders:
Very high-quality laser rangefinders permitted the shooters to confirm target distances with great precision. Birdog uses a Vectronix LRF while Voldoc uses a Leica GeoVid rangefinding binoculars.

Retracting Ballistics Data Tape Holder from Leupold

Leupold Ballistics tape holderIf you often shoot at multiple distances, it’s smart to keep a come-up table (ballistics chart) with your gun. Some guys have a laminated card, while others print out a ballistics chart and tape that to their buttstock. That works, but it’s not a very stylish solution.

Leupold sells a cool, compact Retractable Ballistics Chart that holds your ballistics data on a retractable tape in a plastic housing. Write your come-ups on the tape with a permanent marker pen, such as a fine-point Sharpie. Access the data just like using a measuring tape — pull out to read and then the tape rolls back into the housing. This black plastic, scope-mounted device retails for about $35.00. There are two different versions — part #54804 for 1″-diameter scope tubes and part #54778 for 30mm scopes.

Leupold Ballistics tape holder

Here are some user reviews:

“Much better solution than taping your drop chart to the stock. Just need to be careful of what type of pen you use to write in your data, some felt-tips smear. Has held up fine so far, no complaints.” — R.C., West Virginia

“It serves it’s purpose but $34 is a little pricey. I used masking tape cut down the middle to fit the size of the chart and wrote my come-up values in MOA on the masking tape. That way it is easily changeable without making permanent marks on the chart. Tape pulls out to about 9 inches.”
– D.H., Indiana

“I like to shoot long range and the retractable ballistic chart is much nicer than printing it on tape on the side of my rifle. I use a tactical scope so now I can pull out my ballistic information and set my range without my eye leaving the target. The only problem is pencil smudges, and felt tip will not come off. They need a replaceable print area on the tape.” — B.H., North Dakota
