Happy Holidays to our Readers and Forum Members

Merry Christmas scene

AccurateShooter.com EditorMerry Christmas and Happy Holidays to all our readers and especially our 15,925+ Forum Members. This marks our seventh Christmas “in business”, and the site is growing faster than ever. AccurateShooter.com (and 6mmBR.com) are now accessed by over 100,000 unique users ever week. Part of the reason for that success is the knowledge, experience, and technical expertise that our contributing writers (and expert consultants) share with other shooters.

Unsung Heroes Deserve Recognition
I want to take this opportunity to acknowledge some guys who have really helped out with the site. Number one is JayChris. This dude has been a godsend — he’s a really smart IT guy (and a dedicated shooter) who enabled us to move to multiple dedicated servers this year, and upgrade the forum (twice). I’d also like to thank our regular contributors: German Salazar, Jason Baney, Robert Whitley, Danny Reever, Mark LaFevers, Vince Bottomley, and Laurie Holland. And special thanks to EdLongRange who researches leads for the Bulletin. These guys (and many others) have all contributed time and effort — all without asking a dime in return. I’d also like to thank Joe F. (aka “The Stig”), our designated “master trigger-puller”. When we need someone to wring out the Nth degree of accuracy in a rifle — Joe’s the man.

Thanks to Site Supporters and Sponsors
Finally, I’d like to thank all of you who have made donations (large or small) to the site this year. User support is very important. Donations help us grow the site and provide new services for our readership. We also want to express our appreciation for our many commercial sponsors — from large vendors such as MidwayUSA, Graf & Sons, EABCO, and Midsouth Shooters Supply, to important component-makers such as Berger Bullets, Lapua, and ATK (Alliant, CCI, RCBS). We are all part of a very special community here at AccurateShooter.com — and we appreciate your support!

21st Century’s Impressive New Concentricity Gauge

21st Century Shooting’s all-new Concentricity Gauge looks like a winner. The cartridge case rides on four spinning rollers that allow smooth turning movement with low drag. These rollers are far superior to a set of V-Block supports, or even some ball-type supports.

The amount of eccentricity (run-out) is measured with a high-quality horizontal dial test indicator. In this application, a horizontal indicator works better than the typical vertical dial indicator with spring-loaded shaft used in most other concentricity gauges. We think that, with 21st Century’s new Concentricity Gauge, you can measure cases faster, with less effort, and greater repeatability. In addition, this device can measure the INSIDE of the case neck, not just the OUTSIDE.

Overall, this is a very impressive new tool that is unquestionably superior to many other Concentricity Gauges on the market. Given the capabilities of this device, the price is reasonable: $169.00 including Horizontal Indicator. The Gauge by itself costs $125.00, while the Indicator alone sells for $59.00.

Why the New 21st Century Concentricity Gauge Works So Well
21st Century explains the advantages of its new design: “At 21st Century Shooting, our goal to modernize an industry that has seen little change over the years. The new concentricity gauge is a perfect example. Most conventional concentricity gauges use what is called a height indicator gauge (Dial Indicator with vertical shaft). Although economical, this type of gauge was not intended for the purpose of measuring rotating diameters. The vertical-style indicator can produce inaccuracies due to indicator rod flex and bounce.

Our new Concentricity Gauge uses a horizontal dial test indicator. This type of gauge was designed specifically for checking rotating diameters and in fact is exactly the type of gauge used in the machining industry for decades to measure run out — the very thing that we as hand loaders are striving to minimize or eliminate.

Additionally, our new gauge uses Stainless Steel turning rollers as opposed to fixed bearings or V-block style case supports. You will especially appreciate the roller supports that glide on linear guide-ways. Plus, with a simple push of a button you can adjust the case support base width. No tools are needed to move the base on the built-in guide-ways.”
