The MEC Sizemaster offers simplicity without sacrificing convenience and efficiency. And, it's loaded with premium features. It's the choice of hunters worldwide, bar none.

The highly accurate "Power Ring" collet resizer returns every base to factory specifications. Our new generation resizing station handles brass or steel heads, both high and low base. The E-Z Prime auto primer feed is standard equipment; it dispenses primers automatically.

A single stage reloader that offers this much precision, convenience, and efficiency can only be the MEC Sizemaster.
