“An accurate load starts with quality brass. The more uniform the brass, the better accuracy you can expect. Quality to me is the ability to be reloaded multiple times before the brass begins to show stress signs. We all want uniformity in the shape, weight, thickness, neck tension, shoulders and flash holes. This insures that every round can be loaded to the exact same specs. There are a lot of brass manufactures on the market and several of them are quality. I choose Peterson Brass because of its consistency, quality, customer service, pricing and I like the overall packaging of the product. Since I began using Peterson brass about 7 months ago I’ve notice better numbers on extreme spread and standard deviation.”
