My "gun room" is a spare bedroom with excellent lighting, good storage, and is just a great place for me to hang out, work on my guns, load ammo, and tie flies. I often drink coffee up there, thinking about upcoming hunts & fishing trips, and remember past trips.
The little Hart arbor press in the background is nice to use, for high-quality neck sized hunting and match ammo. I only use it for the .204 Ruger, .25-06 Rem, and the .308 Winchester. It's real portable, I can set it up on any flat surface, am even able to use it at the range!
Seems that anymore, I mostly handload for .45 ACP, .44 mag, .308 Winchester. I concentrated on the .30-06 last year, preparing for the 2016 hunting season, and that worked out real well.
