For optimal accuracy and performance competitive shooters and game hunters prefer using Winchester Unprimed Brass Rifle Cartridge Cases – 50/box for reloading purposes. The company follows a very strict manufacturing regimen designed to produce the best cases available. As part of this annealing is done and as such the cases may have a slight stain near the neck.
There are times when cases arrive with imperfect round mouths due to shifts caused during the manufacturing or shipping process. For this reason Winchester reminds customers that these cases need to be sized deburred and chamfered prior to loading.
