Have done/developed
458 SOCOM
358 CQB
338 Spectre
308 Sabre
500 Phantom

7.62x25 Tokarev
45 ACP

Have worked on a 300 Whisper to make it a little more quiet and portable

Currently have a test mule in a custom proprietary round (not mine) - Tony R has seen it (and has his doubts, as do I)

Starting development for another customer for an entirely new cartridge - sure it will hurt

Waiting on small batch of custom brass for another project, but this one might not fly after all

Have more brass sitting here for one more project once I get some free time

LOWERS?  But WHY?  That is the beauty of the AR-15.  One lower, dozens of uppers, many calibers ....  Heck, I have only 2 lowers in the shop but they are used on all these different calibers.  Only none stock lower is an AR47 bought because it was different ...
