SQL PERCENTILE_CONT over daily-best per-product-per-day observed in-stock prices
Looking at the append-only price history: relative to October 2026 (median $0.630), the current median has fallen 1.6%. These comparisons describe observed movement in the recorded data; they are not a projection of future prices.
The spread between lower- and higher-priced listings (about $0.747 per round here) reflects differences in pack size, bullet type, and brand within the .40 S&W category: bulk cases and basic range loads sit toward the lower end of the range, while small packs and specialty loads sit toward the upper end. The numbers describe what is currently listed, not any single product.
All prices are observed daily-best per-round figures from tracked online retailers, in stock at the time of observation. Coverage varies by retailer and source, and in-store or local pricing is not included. The underlying history is append-only, so past observations are never overwritten. This page reports what the data shows and does not advise any action.
8 frozen months for .40 S&W, March 2026 to October 2026. Each month is computed on its own from that month's observations and then locked; it is a level, not a change from the month before. No calendar month between them is missing a published snapshot. Points are shown unconnected: the set of tracked retailers behind each month was not comparable to the month before it, so no line is drawn between them.
Each month 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. Samples counts every observation in the month, including loads in neither kind.
