INFO on PRIMERS — What You Need to Know

There is an excellent article about primers on the Shooting Times website. We strongly recommend you read Mysteries And Misconceptions Of The All-Important Primer, written by Allan Jones. Mr. Jones is a bona fide expert — he served as the manager of technical publications for CCI Ammunition and Speer Bullets and Jones authored three editions of the Speer Reloading Manual.

This authoritative Shooting Times article explains the fine points of primer design and construction. Jones also reveals some little-known facts about primers and he corrects common misconceptions. Here are some highlights from the article:

Useful Trivia — even though Small Rifle and Small Pistol primer pockets share the same depth specification, Large Rifle and Large Pistol primers do not. The standard pocket for a Large Pistol primer is somewhat shallower than its Large Rifle counterpart, specifically, 0.008 to 0.009 inch less.

Magnum Primers
There are two ways to make a Magnum primer — either use more of the standard chemical mix to provide a longer-burning flame or change the mix to one with more aggressive burn characteristics. Prior to 1989, CCI used the first option in Magnum Rifle primers. After that, we switched to a mix optimized for spherical propellants that produced a 24% increase in flame temperature and a 16% boost in gas volume.

Foiled Again
Most component primers have a little disk of paper between the anvil and the priming mix. It is called “foil paper” not because it’s made of foil but because it replaces the true metal foil used to seal early percussion caps. The reason this little disk exists is strictly a manufacturing convenience. Wet primer pellets are smaller than the inside diameter of the cup when inserted and must be compacted to achieve their proper diameter and height. Without the foil paper, the wet mix would stick to the compaction pins and jam up the assembly process.

For Smoother Bullet Seating — The Dry Lube Option

Forster original caseneck case neck brass dry mica lube lubricator system

If you want smoother bullet seating, inside neck lube can help. Forum member Ackleyman II likes to add a little Mica powder inside his case necks before seating bullets. This is easily done with the Forster three-brush neck lube kit. Ackleyman tells us: “Many loads that I have will not shoot well with a dry neck compared to a neck that is cleaned and lubed with this [Forster Dry Lubricator] — the best $15 you have ever spent.”

The Forster Case Neck Lubricator features three brushes attached to a tough, impact-resistant case with holes for bench mounting. The brushes accommodate all calibers from 22 to 35 caliber. The kit includes enough “motor mica” to process 2000 to 3000 cases and has a cover to keep dust and grit from contaminating the mica. By moving the case neck up and down on the correct mica-covered brush, the neck can be cleaned and lubricated at the same time.

Function: Lubricate case necks for easier resizing
Contents: Kit with base, lid, and three nylon brushes
Lubricant: Includes 1/10 oz. of Motor Mica, enough to process 2000-3000 cases

Neck Lubrication After Ultrasonic Cleaning
If you wet-tumble your cases with stainless media and solvents or ultrasonically clean your brass, you may find that the inside of the case necks get too “squeaky clean”. The inside surface of the neck looses lubricity. In this situation, applying a dry lube can definitely be beneficial. CLICK HERE to see story about ultrasonic cleaning.
