The Target Challenge

What is this and Why should I care?

We here at Apertura Ballistics are engineers and ballistics nerds at heart. The first thing we did during the development of our products is determine a solid way to measure and compare data. Though out testing for the D-Vise we have used 20+ shot groups (5 per target) to compare everything and used spreadsheets for do statistical analysis of the data.

  • Before/After tests on a single rifle

  • Comparisons between rifles,

  • Comparisons between ammo batches

    • brands

    • bullet types

    • bullet weights

For this project we wanted to be as transparent as possible so we decided to share these tools with everyone! Hopefully you will find our methods useful when you are evaluating your D-Vise or just working on your rifle. Don’t worry if you haven’t done any statistics since High School, the tools take care of all the math so you can marvel at the results!!

So you just received your D-Vise…Get Started!!

  1. Download the Printable Target PDF

  2. Take your rifle and head to the range!

  3. Shoot Before/After targets (we recommend 20 rds each minimum)

  4. Save the targets!!!

  5. Download the Calculation Spreadsheet

  6. Follow the instructions in the Calculation Spreadsheet to enter your data

  7. Save it. Print it. Frame it. Use it to flex on your buddies and win beer. Whatever!

  8. Tell us about it you like! Good or Bad, we want to know!!

  9. Sadly forget about all of the South Park jokes I wanted to include in this list
