Ammo Cost And Group Size Debate

Published on October 4, 2025
Duration: 1:47

This video discusses the cost implications of extensive ammunition testing for precision rifle shooting. It highlights that achieving statistical relevance in group size data requires a significant number of shots (minimum 100), which can be prohibitively expensive with high-cost ammunition like 6 GT. The speaker argues against the common misconception that three-shot groups are insufficient, pointing out that scientifically, a much larger sample size is needed for true statistical validity.

Quick Summary

Achieving statistical relevance in precision shooting data requires a minimum of 100 shots (10 groups of 10 rounds). Common practices of using three or five-shot groups are often insufficient for true scientific validity, especially given the high cost of premium ammunition like 6 GT, which can exceed $2.89 per round.

Frequently Asked Questions

What is the minimum number of shots required for statistical relevance in precision shooting data?

Scientifically speaking, a minimum of 100 shots, typically organized into 10 groups of 10 rounds each, is considered the baseline for achieving statistical relevance in precision shooting data. This ensures a robust sample size for analysis.

How much does factory Berger ammunition for 6 GT typically cost?

Factory Berger ammunition for the 6 GT cartridge is noted to be quite expensive, with prices around $2.89 per shot. This high cost significantly impacts the feasibility of conducting extensive ammunition testing.

Why is testing with only three or five-shot groups often considered insufficient?

While common in practice, three or five-shot groups may not provide enough data points to overcome random variations in shooting conditions or ammunition lot consistency. True statistical relevance, as defined scientifically, requires a much larger sample size, like 100 shots.

What is the financial implication of shooting 25 rounds for ammunition testing?

Shooting 25 rounds, often presented as five groups of five shots, can cost between $75 to $90 for cartridges like the 6 GT. This expense is considered significant when aiming to satisfy viewers with comprehensive testing data for videos.
