Common questions about 380 acp brass
- Where is the cheapest place to buy 380 acp brass right now?
- We refresh prices throughout the day and rank every in-stock listing by unit price. Today, in-stock prices range from $5.00 to $59.00 across the 8 retailers we track. The top-ranked listing on this page is the lowest unit price our crawl found in the most recent run.
- How often is this price list updated?
- Listings refresh on an hourly cadence. The "Updated" date in the trust strip above shows when the most recent listing was crawled. In-stock status reflects what each retailer's product page said at that moment — by the time you click through, an item that was in stock may be sold out, especially for high-demand calibers and primers.
- Why are prices so different across retailers?
- Pack size, lot size, and shipping policy create most of the variance. Hazmat fees on powder and primers can swing the effective per-unit cost by 30% or more depending on how many qualifying items you order together. The unit prices on this page already normalize for pack size, but always verify the pack size and shipping fees on the retailer's site before checkout.
- Why is some 380 acp brass out of stock?
- Reloading components — especially primers and certain handgun powders — go through cyclical shortages driven by manufacturer scheduling, ATF transit rules, and election-year demand spikes. We don't surface listings that are out of stock here, but you can subscribe to the back-in-stock alert above and we'll email the moment something hits the shelves.
- Do you sell 380 acp brass directly?
- No — Primers and Powder is an independent price-comparison tracker. We don't carry inventory and we aren't a retailer. Every listing on this page links to a third-party retailer where the actual transaction happens.
