HA! I don't know how I missed that...Yep they are called Lee Loaders.

I started with 30-30 then 30-06 and then .308 with those Lee Loaders.
Wack-A-Mole loader.
You can make very accurate ammo with them.
Only down side for the rifle cases is they Neck size only.
If you got brass that was fired from a large chamber gun you may discover it will not fit your gun after sizing.
Been there done that.
I graduated from those to the Lee Cast iron classic press and Lee dies.
So on Lee's site, that is about $40, and the cheapest Lee single stage press is about $60. Can you still get a die set for about $30?
But if he already has the Lee Loader, then that's not a factor.
If that's the case, components are high but ammo is also high. You can probably save a little money, the question is whether it's enough to be worth the effort.
