The text below from a retired CCI/Speer engineer who once worked for Winchester.
Times are currently tough in the ammunition business. This is the natural and inevitable consequences of over-production coupled with price wars. U.S. consumers simply do not need or want more ammunition in their hoards at this time, regardless of price.
The problem for the ammunition industry is the production capacity never truly goes away. It is usually just redistributed to others at bargain sale prices. In this instance, most of the bullet production equipment will be transferred back to the Winchester plant in Oxford, MI.
