Report from Berger SWN — Wednesday and Thursday Highlights

Berger 2020 SWN Southwest Nationals

Thursday 2/6/2020 was the first Team Day at the Berger Southwest Nationals (SWN). Dozens of squads competed in F-TR, F-Open, and Sling Divisions. This 4-Man Palma Team Match had 15 shots for record each at 800, 900, and 1000 yards. This is a real test of wind-reading and marksmanship. Phil Kelley reports: “Tricky conditions challenged great teams throughout the day.” We first want to congratulate Team Lapua Brux Borden (LBB), with a convincing Thursday win in the F-Open Division. We were especially proud of this performance because Team LBB member Jay Christopherson serves as AccurateShooter.com’s system administrator. Congrats to Jay (far right below) and his team-mates including David Christian, Tod Hendricks, Pat Scully, Erik Cortina (Captain), and Bob Sebold (Coach).

What You Need to Know About Primers — Explained by an Expert

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.

» READ Full Primer “Mysteries and Misconceptions” Article

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:

Primer Priming Tool Magnum primers foil anvil primer construction reloading powder CCISize Matters
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.

Redding Offers New Slant-Bed Concentricity Checker

new Redding Reloading slant bed concentricity gauge

Redding has a new tool that can make it easier to measure case neck and bullet run-out. Redding’s new Slant Bed Concentricity Gauge features a tilted, 4-point case support. The “Slant Bed” design moves the bearing surface down and away from the user, making case rotation easier. Redding explains: “Pushing down with the index finger is a natural movement as opposed to rolling on a flat which requires the movement of the entire arm. It improves both the ease of case rotation and the maintenance of proper alignment for reading.”

The orientation of the Dial Indicator also improves ergonomics. The fixed vertical indicator stand places the indicator face at the optimal sight angle of 30°, reducing the possibility of off-center readings. Precision stainless steel bearings provide single-point contact with the cartridge case. Bearing sliders on stainles guideways allow quick and easy linear adjustment for cartridge length.

Redding’s new Slant Bed tool is affordable — $124.19 with 1″ Dial Indicator. The tool ships set-up for right-handers, but quickly converts for left-hand use.

- Ergonomic Design — Ships complete with large 1″x.001″ dial indicator
– Fixed indicator position — Dliminates set-up errors
– Precision stainless steel bearings mounted on linear guideways accept cartridge sizes from .17 Hornet to .408 CheyTac.
– Supplied with non-skid rubber feet or use direct mounting holes
– Easily converted to left-hand arrangement

Redding Product Description:
The new Slant Bed Concentricity Gauge features a large, easy-to-read dial indicator which quickly mounts in a factory aligned base dead-on the centerline of the case. No additional indicator alignment is needed. The uniquely angled design of the slant bed also better positions the dial indicator for easier reading as opposed to older designs. Additionally, the Gauge can be transitioned from right-handed use to left-handed by using a provided set of mounting holes on the base. Simply remove the mount screws and transfer the working sections from one end to the other. Left-handed users no longer need to struggle to get accurate readings.
