I made a bunch of 17 Mach IV - Mach 4 brass for a rifle. I ended up selling the rifle, so the brass is now available.
Total LC Nato available is 666, total LC 223 marked 203.
LC Nato stamp brass, total available is 666, $80 first 100 shipped, $75 per additional 100
LC 223 with 203 count, total $160 shipped

As with my 20 Vartarg brass, I made these from Lake City, as it's very consistent, and long-lasting brass.
I have 666 of them made from Nato stamped brass which weigh the same, though different year stamps, all compatible.
203 made from the LC 223 marked brass, which also weighs the same as the Nato, but different marking.
Both groups weigh in the same average weight, about 83.6-85.0 grains, so they could all be used together and give very accurate results, or you could only get the Nato marked, or only get the LC 223 marked.
You could also use the brass in 17 Fireball chambers, as they are almost the same, just size and load.
The brass was carefully formed through many steps, final sized with Redding dies. They have neck thickness of .0125"-.0130" are annealed, and the primer pockets were uniformed with K&M uniformer. Trimmed to 1.400" +/- .005" so usable in 17M4 and 17FB
