So I opened up a new bag of 300 Win MAg brass tonight and was thoroughly disgusted with what I saw. Almost every round had heavy tarnishing (possibly even pitting) where the neck and shoulder meet, some had it the full length of the case and some on the case head. Numerous cases also had a flash hold that was not centered in the primer pocket. Has anyone else noticed a decline in the quality of brass from Winchester lately? I have a new bag of 218 Bee and 22-250 yet that I am dreading opening. I have always used their brass and have never had issues with this yet. The brass I bought last year was still good. I am thinking it may be time to change manufacturers.
