Mec 650 Reloader Problems With Primer

The primer ignites the powder. When you pull the trigger, the hammer falls on the firing pin. denting the primer cup. This causes the component in the primer to detonate, igniting the main powder charge.

Different primers have different characteristics depending on their purpose. Use only the primer that is recommended by the component manufacturer for the hull, powder, wad, and shot load you are using.

To make reloading safe, all it takes is common sense and the ability to read and follow the directions of the various component manufacturers.

When you purchase your powder, get a copy of the "SAAMI" (Sporting Arms and Manufacturers Institute) pamphlet on the properties and storage of smokeless powder. Read this literature and abide by it. Generally speaking, powder is safer than gasoline, because unlike gasoline, it does not give off explosive fumes. If ignited, powder will burn until it consumes itself. Modern smokeless powders must be confined to cause an explosion. The containers that powder is purchased in are designed to burst without causing an explosion if the powder is accidentally ignited. Your powder should be kept in these containers until it is used up. It is unsafe to put powder in a glass jar or bottle or any other container which could cause pressure buildup. Store your powder where there is no chance of sparks, fire or flame, where it is cool and dry, and where children cannot reach it.

Primers also require care in handling. Never take primers from the container that they come in until ready for use. Storage of primers in anything but the container that they were purchased in is unsafe. Exposing a primer to excessive heat, or to fire, flame or rough handling will cause it to explode. Do not store primers near your powder or where children can get at them.

When a manufacturer tells you to use a particular set of components in a shell it means precisely that. You cannot indiscriminately experiment with or substitute components without experiencing problems. At best, you will get a shell which fails to give the performance you expect. At worst, you may inflict serious injury upon yourself or someone else who fires your reloaded shells. The manufacturer has extensively tested recommended loads and knows how they perform. Always follow these recommendations exactly.

It is also highly recommended that safety glasses be worn when reloading.

When finished reloading, remove the containers from your machine and seal them with caps and put them in a safe place. Also return all primers to their original container and store them in a safe place. It is important that these materials are kept out of the reach of children and other unauthorized persons.

Shotgun Shell Reloading Diagram

After removing your new reloader from its carton, inspect it carefully for damage, in addition to the reloader itself, you should have these additional parts shown in Photo #3.

Before you actually try reloading, we recommend that you look over your loader and compare it with this diagram identifying all the parts and dies you'll be using.

A. CHARGING BAR is located just under the powder and shot containers.

B. AUTOMATIC-CYCLE MECHANISM. Each stroke of the handle automatically moves the charge bar to left or right measuring and charging precise amounts of powder or shot into the shells.

C. WAD PRESSURE INDICATOR gives exact amount of pressure actually being applied to the wad column at the bottom of the handle stroke.

D. WAD HEIGHT INDICATOR used to disclose improper wadding.

E. DEPRIME at which the shell opening is ironed and spent primer is ejected.

F. AUTOMATIC PRIMER FEED positions primers in shell carrier with each stroke of the handle.

G. REPRIMING STATION at which shell is also charged with powder. Spring tension automatically applies the proper pressure and compensates for variations in height of base wad while seating primer.

H. RAMMER TUBE is used to seat the wad column and through which shot is also dropped into the shell.

I. SPINDEX™ CRIMP STARTING with swivel action to correctly align with the original shell creases. Can be changed from 6-8 pt. in seconds.

J. CRIMPING STATION with the exclusive cam-operated two stage crimping apparatus. Die is adjustable for depth of crimp. (Not Shown)

K. RESIZING AND FINISHING STATION radius may be adjusted to suit individual taste. (Not Shown)

L. SHELL CARRIER into which shells are placed and which automatically position each shell at the proper station.

M. PRIMER CATCHER which is secured into position at the base.
