What the .357 Magnum price data shows
Across the trailing 30 days, .357 Magnum ammunition has a median observed price of $1.232 per round. The middle of the market — the 25th through 75th percentile of daily-best prices — runs from $0.698 to $1.649 per round, while the full observed range spans $0.330 to $2.848. These figures come from 292 distinct products listed by 19 tracked retailers, with data on 31 of the last 30 days.
Looking at the append-only price history: relative to June 2026 (median $1.399), the current median has fallen 12.0%; and against April 2026 (median $1.550), it has fallen 20.5%. 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 $0.952 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.
