I loaded a ton of 12g on a cheap LEE press until I found a used MEC 600 jr, if you want to load 00 buck I think you have to drop the pellets by hand because I dont think any press will meter them. I use a piece of aluminum arrow shaft cut to length with a plug in on end that I fill with 00b pellets fill it to the top, that way I get the right number of pellets, I put the pellets in a pan and let them roll into the tube.
