Camp Perry National Matches EIC Rimfire Service Pistol .22 LR Competition NRA CMP

The rimfire/centerfire pistol competitions begin on July 15, 2024 with the handgun Small Arms Firing School (SAFS) followed by M9 Pistol Excellence-In-Competition (EIC) pistol matches. The SAFS will be led by USAMU, Military Team, and CMP instructors. Following classroom instruction and practice on the range, SAFS participants will fire an M9 EIC Match with the goal of earning points towards the prestigious Distinguished Badge.

On July 17, the .22 Rimfire 900 Aggregate, Team Matches, and Rimfire EIC matches will be held. In the past, these matches have been hugely popular — with 480+ Rimfire competitors from novices to experts.

Following the rimfire pistol matches, there will be centerfire Pistol Aggregate and Team Matches on July 18, followed by .45 Pistol Aggregate and Team matches on July 19. Then, on Saturday the 20th, the big President’s 100 Pistol Match, National Trophy Individual Match, National Trophy Pistol Team Matches, and GSSF Glock National Challenge will be held. There will be plenty of talent on the firing line. In recent years, over 90% of the top 50 Service Pistol shooters were Distinguished. The last pistol matches run on Sunday the 21st, with Pistol Games Awards at the end of the day.

How to Disassemble, Clean, and Re-Assemble Jewell Triggers

6.5 Guys Jewell Trigger assembly disassembly maintenance cleaning

Jewell triggers are still the most-used triggers on competition benchrest and F-Class rifles and they are also popular for hunting, varmint, and tactical rifles (with or without safeties). While a Jewell trigger can work for years with minimal maintenance, if the trigger becomes gunked up, it may be necessary to disassemble the trigger for a thorough cleaning. Our friends Ed and Steve, aka the 6.5 Guys, have produced a helpful video that shows how to disassemble and then reassemble a Jewell trigger.

Why You May Need to Disassemble Your Jewell Trigger — the 6.5 Guys
Jewell triggers are a popular choice in the sport of long range precision shooting, and like everything else require regular cleaning and maintenance. In most cases they can be cleaned with charcoal lighter fluid or dropped into an ultrasonic cleaner. Should the situation require, they can be completely disassembled according to the Jewell Trigger Manual.

We ran into a situation where we had to dissemble a trigger due to the entrapment of some sticky dirt that couldn’t be removed with an ultrasonic cleaner. Our first step was to find some step-by-step instructions but we couldn’t find anything.

Recognizing that other shooters might be in the same situation we produced a step-by-step guide and video, published in full on 65Guys.com. These instructions will work with a left- or right-handed trigger. In our case we worked with a left-handed BR model trigger with safety and bolt release.

Step-by-Step Instructions are provided on 65Guys.com website. We recommend you read all the instructions carefully before you even think about disassembling your trigger. This video explains the process so you can get a sense of what is involved.

Bullet Sectional Density — What You Need to Know

Bullet projectile sectional density formula Sierra Bullets

by Sierra Bullets Ballistic Technician Paul Box
All of us who have been in reloading and shooting for any period of time have read how sectional density has been regarded as a bullet’s ability to penetrate. Back before high velocity came along and modern bullet design, the easiest way to get more “power” and penetration was by increasing the diameter and mass. After all, a bowling ball will hurt more than a golf ball, right?

Let’s take a closer look at sectional density.

The formula for calculating sectional density is pretty simple and straight forward. Take the bullet weight and divide by 7000. This number is then divided by the bullet diameter squared. Two bullets of equal weight and the same diameter will have equal sectional sectional density. No regard is given to the bullet construction. This is where the fly hits the soup in considering sectional density as far as penetration is concerned.

Section Density Formula: (Bullet Weight divided by 7000) divided by Bullet Diameter squared.

Bullet construction is the biggest factor in how it is able to penetrate. The best example I can think of here is to look at the Sierra .224 55 Gr. FMJBT GameKing #1355 compared to the 55 Gr. BlitzKing #1455. Both are .224 and weigh 55 grs. Both have a sectional density of .157. But there is a huge difference in their construction. The FMJ has a thick jacket and is designed to penetrate. The BlitzKing is designed for fast and rapid expansion with little concern for how deep they will penetrate.

The next time you’re choosing a bullet, look at the construction and less at the sectional density number. It’s all about the construction anyway. If you have any questions or would like to discuss sectional density or bullet penetration further, please give us a call at 800-223-8799 or shoot us an email at sierra@sierrabullets.com.
