September 2026 Price Summary

MetricPrice Per Round
Lowest Observed$0.307
Range / practice median$0.660
Premium / defensive median$1.20
Highest Observed$3.25

The table shows two medians: range / practice loads (FMJ-class) and premium / defensive loads (hollow points, hunting and match). A single median across both would depend on how many of each kind the tracked retailers listed that month, so it is not shown. A dash means that kind had fewer than 15 observations in the month, or the month has no split.

Based on 7934 observations over 30 days across 19 retailers · 297 products tracked. The observation count includes loads in neither kind.
