When an old man dies, a library is lost forever...
Building supply stores sell butcher block counter top in 4 6 8 10 foot sections. Not expensive and pretty durable. You might consider getting a side cabinet like the one on the left in pic, and spanning the space between the two. Gives you the legroom for a seat.
I used two bottom cabinets without wheels in my shop for tools. Siliconed wood to the top, siliconed a 2nd hand Corian countertop to the wood, put weight on it until cured. It’s super solid.

My reloading room is too small… I use a walk in closet for an RCBS press mounted on a Shop Fox small work bench. That bench isn’t quite as solid as I’d like, but it works fine.
