I've been looking for 300 WSM brass and all I can find is Nosler and Norma in 25 piece counts. What ever happen to the Winchester brass that came in the 50 or 100 piece bags at half the cost? I've looked at MidWay USA, Cheaper than Dirt, Cabelas, Scheels, Sportsman Warehouse, Sportsman guide, and Gander Mountain with no luck. Anybody else have any places they know of that sell brass?
