If I set this up for a straight walled, revolver cartridge, like a 32 S&W or 38 Special, I will not need to worry about case trimming.
So I'm learning heavily towards the Lee hand press (lots of options for dies and not too expensive). Maybe a hand priming tool (this adds another tool to the kit but I'm thinking it's worth it to avoid priming on the hand press?)
A powder funnel. A powder dipper made for the one charge of the one powder being used. A carbide sizing die (eliminates the need for lubing the cases). And seating & crimping dies. The loading block will be incorporated into the box that contains the tools/components.
The limiting factor will probably be the number of bullets and primers in the kit.
Federal Primers come in oversized packaging, so they are probably out. Winchester or CCI primers have more compact packaging BUT I don't think I want 1000 bullets to go with 1000 primers.
I'll need to find the ideal compromise between the number of bullets in the kit and match that to the number of primers in multiples of 100.
I'm thinking that in terms of weight and bulk, I'm going to be in the range of 300-400 bullets if we're talking 38 Special; maybe a little more if it's 32 S&W bullets.
If the capacity of the kit is 400 rounds, I don't need an entire pound of powder in the kit. And because I'll be using a dipper, it would be nice if the powder was in a large, shallow container with a wide mouth. I'm thinking a short, wide plastic screw top jar for the powder. That will take up less space in the kit and be easier to fill the powder dipper from.
I welcome input from others.
