Thanks all.
As far as pictures, right now, there's nothing there. No light in it yet - waiting for the electrician to come out. The walls are 14" because it's in the garage and the builder told me not to grade the lot, which is on a hill. Hadn't thought about a loft.
I'll have a 44" wide Drake safe in there, and probably one of my current off brand safes - about 18x22. No rifle racks. The room is made of 2x4s, insulation, and drywall. It'll have a security door, but that's it. We're out in the middle of nowhere, and there are plenty of breaching tools in the garage.
I read up on the bench height thing last night. My current bench is a Gladiator that is too low - requires me to drop my shoulder down with each stroke. Right now, I only have the Hornady LNL AP. Works for all of my current needs. Might get a single stage in the far future, and maybe a shotshell press. I'm building a 300 yard range, so I plan to do a lot more shooting, if I can afford to after buying everything I need to for this place. I like the idea of an island to lay weapons on for cleaning, maintenance, etc. My current brass storage solution is Ziploc tubs. Works so far, and I like that they are see through. My current ammo storage is a rolling Gladiator locker box. I like the idea of being able to roll it out in case of a fire, but not sure that is very practical or realistic with several thousands of rounds in it. I currently store all my reloading tools and supplies in a Gladiator wall box - dies, shell plates, powder, primers, bullets (at least as much as fits), books, etc.
One of my issues currently is all the dust from tumbling. I want to stay with the tumbler. Thinking about building a specific area just for the tumbler with the ability to enclose it. I'll just vacuum out the dust with a shop vac.
I also plan to use a T-track system like the one on Ultimate Reloader. Seems to be a pretty convenient way to move tools around. On the other hand, I may not need it, and instead just have several different locations that I move to in order to perform certain tasks. I like the peg board idea for storing shell plates and rotor plates for the auto feeders.
