Frequently Asked Questions

MEC's Powder Bushing Chart shows the volumetric capacity of a given powder in relationship to various powder bushings. The amount listed on the MEC Powder Bushing Chart was calculated using a single stage machine with a standard lot of a given powder. A single stage reloader will generally throw a slightly heavier charge than a progressive machine. The information supplied in some of the reloading guides may have been calculated using a progressive machine. For this reason, MEC always recommends the use of an accurate scale to verify the amount of powder dispensed. Other factors can also affect the amount of powder dispensed.

The resizing collet may be dry. Use Anti-Seize lubricant on the outside of the collet fingers.
There may be shot or powder buildup inside the collet.
Wad guide may be set too low on progressive reloaders.

Grommet may be missing or need to be replaced.
Brass washer missing on the powder side or installed incorrectly.

On progressive reloaders, lower the powder, or reprime tube, slightly.

Charge bar may not be returning back to the right every time.
High antimony or hard shot will throw a lighter charge.

Make sure that the charge bar is completely traveling to the left and to the right every time.
The bushing chart will supply the information of recommended bushings, but due to many factors, charges may vary and the use of a scale is highly recommended.

The brass washer has four dimples on it that should face up into the rubber grommet.
With the rubber grommet and the brass washer installed, the powder should not leak out of the measure assembly.

There are no longer any parts available for the old 300, 310, and 400 reloaders and no parts are interchangeable.
The 250 has been out of production for over 40 years. There are no longer any parts available for this reloader and the current parts will not retrofit onto the 250.

The old style, '76 model Grabbers will not resize high brass shells whereas all of our current reloaders will, such as the Steelmaster.

A steel shot kit and charge bar must be installed for reloading steel shot.
Once the kit is on, you will only need to change the charge bars when you go back and forth to lead shot.

The Universal charge bar is an aftermarket product which is made to work on all of the MEC reloaders. Information on the Universal bar can be obtained by calling Multi-Scale Co. at 1-905-566-1255.
