The lee press is mostly plastic and is OK for loading a few boxes a year. I have 2 MEC 600 Jr. presses. One in 12 ga and one in 20 ga. I have loaded about 10,000 rounds on each without a single problem.
For 20 ga. I use the 7/8 ounce charge bar that came with the press and unique powder with remington rxp20 wads. My presses came pre-adjusted and load most hulls uniformly. The 20 ga. press does not like Federal hulls.
I mostly load remington and winchester hulls.
Hope this helps.
