I am going to begin reloading 22-250 with a guy who already has all the components and reloads 243. So I went out and bought unfired brass, bullets, primers, and the Lee Deluxe Die Set (neck sizing collet die, dead length bullet seater, and full length sizing die). I know I need powder, but I'm going to try his first and see if I want to stick with that brand or try another. I've been shooting factory Hornady 50g V-Max, so I have 30 of those once fired casings in case I can use them to match the neck size to the new cases.

I've been trying to do as much research as possible and reading the instructions that came with the Lee Die Set, I'm wondering if I'll need any of the following:
depriming die?
case trimmer?
debur tool?
chamfer tool?
case holder?

And are any of the above universal such that if he already has a tool for 243 would I be able to use it with 22-250?

thanks for the help
