Dopin a Rifle With Gravity Ballistics - MDT Mention

What happens when you get to the range and your Kestrel dies, and you don't have access to your ballistic data? Or maybe you can't afford or haven't yet purchased one? The ability to shoot long-range shots shouldn't be hindered by expensive equipment. There needs to be a simple solution. YouTube Channel SHLowlight answers this question in a short video titled "Dopin a Rifle with Gravity Ballistics."

Branded "Gravity Ballistics," the host, Chris Wray of Rifle Kraft, records his process for checking and confirming ballistic data with just a calculator app on his cell phone and targets at known distances. This simple method is designed to aid shooters who don't have the latest tech or are in a situation where they can't reference their data.

HOW TO USE GRAVITY BALLISTICS

Before commencing, confirm zero (at 100 yards). If you don't, then this exercise is futile. On average, most short-action cartridges used for precision rifle shooting require one mil of elevation adjustment at 300 yards (plus or minus a tenth). To begin, shoot a 300-yard target with one mill of elevation dialed. In the video, the shot landed center mass. Based on this successful impact, simple calculations can be used to gauge the needed elevation at further distances. The video does not articulate how the formula was derived but gives you the answers (300 yd data X 1.75 = 400, 400 yd data X 1.45 = 500, 500 yd data X 1.40 = 600m 600 yd data X 1.30 = 700, 700 yd data X 1.25 = 800, 800 yd data X 1.24 = 900, 900 yd data X 1.22 = 1000). The point is that all you need is your phone's calculator.

Next, the Chris moves to shoot a 600-yard steel target after adjusting for elevation based on the one mil hold at 300 yards (1.0 X 1.75 = 1.75 [400], 1.75 X 1.45 = 2.5375 [500], and 2.5375 X 1.40 = 3.5525 [600]). One shot is taken and lands directly on target, further confirming the "Gravity Ballistics" being used are valid. This 600-yard shot is used as Chris's standard accuracy and math confirmation. The same method is used at 700 and 800 Yards using the abovementioned calculations. The hosts then connects on a 900-yard target (after a windage correction), showcasing the simplicity of Gravity Ballistics.
