I did have a very large quantity of brass that had those same issues, but since I handload and none of those issues were detected at the time, I am assuming the ones that failed after sizing were due to my negligence. Now regarding the ones that failed after first fire, I have to agree that some have had those same issues. But, for now I am taking the responsibility for the failure on my part. I can definitely show you at least 50 cases from about 6 different boxes and manufacturers that have cracks in various places after first fire. That factory ammo lot was approximately 3 years old. Not sure if that means anything.This has nothing to do with the 25-06 but more to do with factory ammo quality from the last 5+ years. I have let friends/acquaintances check the zero on their deer rifles at my private range before season the past few years. These are not guys who handload, only buy a box or two of factory ammo every fall. My stipulation is that they give me all the empty brass when finished. Most is 30-06, 308, 243, 30-30, etc. I can't believe how many cases out of a box of twenty have split necks, pin holes in the shoulder/neck junction, and creases in the case body. I'm not impressed with the current brass quality from domestic ammo producers.
