Hello All
The headline is eye-catching, I know.
I have a question for all the reloaders and statisticians. I'm reloading for several AR pattern rifles. I started reloading with the express intent of bulk, long term, shtf style storage. Now that I'm comfortable with my reloading skill, I wanted to take on a larger project. Having several AR's, I want to develop a load that is PRECISE across all of my rifles. To do this I was thinking of doing the following:
You can assume that,all else being equal, the only changes that will be made are powder loads.
1. Work up five loads of 20 rounds each, totaling 100 rounds for each individual rifle being tested.
2. Shoot each load in each rifle to find the most precise load by grouping.
3. Average the size of the groups across the range of tested rifles.
4. Use the averages to develop another set of 5 loads, 20 rounds each.
5. Rinse, repeat steps 1-4 to perfect a load that will give the best groups across the range of rifles tested.
6. Use the perfected load to manufacture bulk batches of ammo.
I must state again that the purpose of this testing is to develop a load that will give the best groups across the range of rifles tested. Then use that load to stock ammo for a rainy day. Does anyone see a flaw in my methodology? Any recommendations to improve or streamline the process? Comments? Critiques?
