.357 Mag Market Analysis
.357 Magnum's market price index compares posted prices for the same products over time, whether they are in stock or sold out. The latest index is 0.3% above 30-day avg. The current signal is HOLD; it measures market pricing, not a discount on an individual offer.
The index starts at 100 for each comparable series. Price changes are combined using equal-weight geometric price ratios. New or disappearing listings do not create a price change. If no products match between observations, the chart starts a separate series and does not infer a return across that break. Available records span 2026-04-05 through 2026-10-26.
For shopping now, the lowest in-stock price is $0.511 per round at Gun Place. 143 of 206 current listings are in stock across 34 retailers.
Quotes come from the existing retailer checks. Dates without observations are not filled in. Posted dollar medians are available in the history table; unlike the index, they can change with the product mix. Prices exclude shipping and tax. Check the retailer's page before purchasing.

Is .357 Mag ammo a good deal right now?

How many retailers sell .357 Mag ammo?

What does the .357 Mag price chart measure?
It tracks price changes in matching products, including sold-out products. Each comparable series starts at index 100; 105 means a 5% increase within that series. The daily table also shows actual posted median prices per round. Product mix can affect the median; the matched-product index controls for that.
Should I buy .357 Mag ammo now or wait?
BUY means the market index is at least 10% below its 30-day average. WAIT means at least 10% above it. HOLD means between those thresholds; it does not mean prices are perfectly flat. These describe observed prices and do not predict future prices.
What does CPR mean for ammunition?
CPR means cost per round: the package price divided by the verified round count. It lets you compare different box sizes. The market index is a separate measure of price movement, not a dollar price.
