Reforming WSM to WSSM brass
We use custom dies to reform WSM brass of any caliber to 223 WSSM, 243 WSSM, 25 WSSM, and 300 OSSM. To form the WSSM from WSM, the cases go through 5 form dies, they need to be trimmed in the process, and the necks need to be reamed due to the increased brass neck thickness created in the forming process. Finally, our brass is annealed.
Our goal is to maintain WSSM brass in stock ready to order. Here are a couple of photos of interest.
