    The MarketFlat Prices, Missing BrandsNot one canister powder went up in price this month. The story is what is not on the shelf: Alliant at 7% availability, IMR at 12%, Norma at zero — while Hodgdon, Vihtavuori and Winchester sit at 60–80%.99.5 RCM index$49.00 Median shelf price7 ↓ Price moves

    HandgunTitegroup CountryThe fast pistol shelf is two markets. Hodgdon, Winchester and Vihtavuori were there every day at $38–48 a pound; fourteen powders — most of the Alliant line, Hodgdon's Clays family, True Blue — were not there at all.44 Powders in the band30 In stock every day14 Never in stock

    Large HandgunH110 Never LeftThe magnum-pistol shelf is the steadiest in the market: thirteen of sixteen powders in stock every day, Hodgdon at 83%, prices exactly where August left them.

From the desk

This is the first issue of The Monthly Grain as a magazine. The market report that ran on the Powder Desk on 27 September is here as the General edition, and the same month's data is now cut four more ways — Handgun, Large Handgun, Small Rifle, Large Rifle — by position on the merged burn-rate chart, so that the page you read is about the powders you buy.

Every number comes from prices and stock flags we collect ourselves each morning. Nothing is estimated, nothing is back-filled, and no load data appears anywhere in these pages. Where a figure is one retailer's clearance rather than a market price, it says so.
