I have had similar experiences with WINCHESTER brass. I have even gone to using different brands of primers that are slightly larger to compensate for the primer pockets that are too sloppy to hold my usual primer. Inconsistent primer pocket depth is also a problem from batch to batch, and protruding primers are a real concern especially with tubular magazine lever-guns.
Neck deformation has resulted in a number of throwaways (as much as 5%), and my .348 calibre doesn't have many supplier options.
Very unimpressive production standards from a company that rides heavily on its name.
Smarten up Winchester!!!! and yes I have written a letter of complaint.
