Question:
I collected some rifle cases for a specific model that I shoot from a local range. After inspecting and trimming for proper length I tried the 'Plunk' test on my firearms chamber. As I suspected the rifle that fired these case must have had a wider chamber so these cases will NOT fully engage my rifles chamber. I tried running a few through my die for that caliber and they all tend to get stuck in the die even when properly lubed. They are just to big from about ⅔ of the way down the case to the ejection groove.
My question… Would it be advisable to anneal the entire case or just the lower ⅓ of the case and then run them into the die set? Any adverse affects to this process?
