Frequently Asked Questions
Why does the MEC Powder Bushing Chart differ from those printed in some of the reloading guides?
- 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 general 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.
Why does my reloader jam, or bottom out, half way down on the downstroke?
- The resizing collet may be dry. Use Anti-Seize lubricant on the outside of the collet fingers.
- May be shot or powder buildup inside the collet.
- Wad guide may be set to low on progressive reloaders.
What can I do about powder leaking out the top of my bar?
- Grommet may be missing or need to be replaced.
- Brass washer missing on the powder side or installed incorrectly.
Primer not fully seated.
- On progressive reloaders, lower the powder, or reprime tube, slightly.
Why is my charge bar throwing a lighter charge of shot from what it should drop?
- Charge bar may not be returning back to the right every time.
- High antimony or hard shot will throw a lighter charge
Why are my bushings dropping different from what the bushing chart states?
- 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.
Powder is leaking from bar. Both brass washer and brand new grommet are inserted.
- 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.
Can I still get parts for the MEC 250, 300, 310, or 400? Are any parts interchangable?
- There are no longer any parts available for the old 300, 310, and 400 reloaders and no parts are interchangable.
- 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
My grabber is set up to load 2-3/4" shells. Is there a kit to convert it to 3"?
- The old style, '76 model Grabbers will not resize high brass shells where as all of our current reloaders will, such as the Steelmaster.
What do I have to do to safely change from reloading lead to steel shot and back again?
- 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.
On a MEC 8567 Grabber can a Universal charge bar be installed on it? Is this charge bar ok to use on this reloader?
- The Universal charge bar is an after market 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.
