RE: Spaces Needed
When I started 20 years ago I had a two drawer filing cabinat that heald everything, but I only loaded 30-06. Primers in one drawer and 4064 in the other, rockchucker, 505 scale, and all the other goodies. Today I'm lucky to fit my gear in one room. My house catches fire run, cause it's going to the moon. Today I have dual craftsman steel benches 5 foot each, 3 shelves above it 10 foot each and I still need more room. I load 20 different cals and compete in action pistol with 9,40,357Sig, and 45 so I have 1000's of bullets, brass, primer, and four to six 8lb kegs all over not to mention rifle powder's.
You can get by with a filing cabinate but I don't recomend it, at least get a craftsman bench.
