My discussion of underground target ranges below jiggled a little pessimistic memory floating between my synapses of a piece I read in the mid-90s in "The Blue Press," a catalog/magazine put out by Dillon Precision Products, Inc. of Scottsdale, AZ.
Back then, I cut and pasted Blue Press pages into a leaflet and distributed it to gunstores and other gunnie gathering places. Since then, the editor, Mark Pixler, has been kind enough to allow distribution on the Internet.
It is a cautionary tale, set in a future where we have lost. You will find it here.
Read it, and then, if you do not wish to live in that grim place, go back to getting ready for the upcoming fight.
