What the .357 Magnum price data shows

Across the trailing 30 days, .357 Magnum ammunition has a median observed price of $1.20 per round. The middle of the market — the 25th through 75th percentile of daily-best prices — runs from $0.720 to $1.60 per round. The full observed range spans $0.307 to $3.25. These figures come from 325 distinct products listed by 21 tracked retailers, with data on 31 of the last 30 days.

Looking at the append-only price history: relative to August 2026 (median $1.20), the current median has held roughly flat. 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 $0.878 per round here) reflects differences in pack size, bullet type, and brand within the .357 Magnum 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.
