MEC Sizemaster in 12ga

By Mark O. on Dec 07, 2020
This is my first shot shell press. After a ton of research this is the best value for the speed and quality of all the single stage presses IMO. Very easy setup with help from all the videos online. The primer feed is a must have in my opinion and the collet resizer is smooth as butter.

MEC is one of the most widely use presses so there is always someone to share information with and get tips/how to's. Powder bushing that come with it are fine to get you started for a good number of target loads. All in all the Sizemaster is a solid choice and I don't think you can go wrong with it. I can average 6-7 boxes an hour at a medium steady pace which is fine for me.

Great reloader - easy on the shoulder, adjustable, and almost impossible to make a mistake!
