Just saw some Winchester SP standard at Cabela's. It surprised me. Usually they just have Magnums in CCI and Winchester.
One note about Win SP magnum primers. They are the hottest by far. Noticed this over many years. Even Accurate Arms old manuals said to reduce loads a full 15% when using them. Winchester .357 Mag. ammo in past years was always very hot loads. Using ball powder to boot.
