well, riflewoman got me started down this trail... and look where it led:
from Orbital ATK, the contractor operating LCAAP since 2000:
"... In addition to manufacturing ammunition for the DoD, Orbital ATK’s Lake City facility also produces high-quality ammunition for commercial customers, ..."
"... All Lake City ammunition, whether for military or commercial use, is manufactured in the same facility, utilizing the same processes and quality-control standards. Orbital ATK partners with several commercial companies to provide cartridges and components for their ammunition needs. As a leader in aerospace and defense technologies, Orbital ATK and the Lake City facility maintain the critical skills, personnel, and technical manufacturing capabilities essential to successfully deliver high quality, small-caliber ammunition from development to production.
Our commercial partners include:
- Federal Cartridge – We are excited to continue our longest standing and largest relationship with Federal Cartridge, supplying AE .223, XM855 Green Tip and XM193 5.56x45mm cartridges for the commercial market.
- Hornady – The combination of Hornady projectiles with the famous Lake City brass allows the shooting public access to a wider offering of bullet weights and types including FMJ, Spire Point and Boat-tail Hollow Point in both .223 Remington and 5.56x45mm cartridges ranging from 55gr to 75gr.
- Fiocchi USA – Lake City will be providing .223 Remington cartridge cases manufactured with the famous Lake City brass to Fiocchi USA for cartridge assembly and packaging at its facility located in Ozark, Missouri. ..."
i shoot alot of the fiocchi .223. i have identified 3 distinct types of brass... the largest difference being between the 'shooting dynamics' line and the 'extrema' line. i have repeatedly seen the difference on paper, with the extrema being better. the headstamps on one have G.F.L. and on the other GFL. Then there is a variation with smaller font.
so, i guess i unwittingly asked somewhat of a trick question. kinda like asking which powder do you find more temperature sensitive: W760 or H414?
