“We noticed in the forecast that the wind conditions were going to be mild, and there was a chance to set a new National record”, commented Team Captain Erik Cortina. “The previous record was an 800-42X, so we knew we all had to shoot perfect scores to claim the record. It felt great when the 80th shot came up an X! We managed to score 800-53X, beating the old record by 11 Xs.”

Additionally, team members Jay Christopherson, David Christian, and Erik Cortina finished in the top 10 of the individual F-Open LR championship. Along with its record-breaking Long Range 2023 win, Team Lapua finished 3rd place overall in the Mid-Range F-Open team championships, adding an exclamation point to Lapua’s dominating results.

The 2023 United States F-Class Long Range National Championships were hosted by the Desert Sharpshooters and held November 1-5, 2023 at the Ben Avery Shooting Facility in Phoenix, Arizona.

Getting Started in F-Class — F-TR & F-Open Recommended Gear

Vince Bottomley Target Shooter F-Class F-Open F-TR

On the heals of the USA NRA F-Class Nationals held earlier this month in Phoeniz, we’ll take a look at the gear used by F-Class competitors who shoot in F-TR and F-Open divisions. On the firing line you’ll see the latest and greatest stocks, actions, optics, bipods (for F-TR), and Front Rests (for F-Open). This article looks at the two F-Class divisions.

A while back, our friend Vince Bottomley in the UK wrote an excellent article for Target Shooter Magazine. Vince offers “solid-gold” advice for new F-TR and F-Open shooters. Vince reviews the cartridge options, and offers suggestions for a shooter’s first (and hopefully affordable) F-Class rifle. Vince also reviews various bipod choices for F-TR and discusses optics options (from $300 to $3000).

Here’s a short sample from the Target Shooter Magazine article:

Getting Started in F-Class by Vince Bottomley
As membership secretary of a large club, one of the questions I’m frequently asked – “What’s the best way to get started in F-Class?” My club has an F-Class shoot every couple of weeks at ranges from 300 to 1000 yards and, not surprisingly, it’s very popular.

F-TR or Open Class?
From a shaky start way back in 2004, the F-TR Class is now proving as popular as Open Class and, at GBFCA League shoots and club shoots, many shooters choose to start with a 308, shooting off a bi-pod – in other words F-TR. In Open Class, the 7mm WSM soon established itself as the “must have” cartridge – if you wanted to win but, the WSM’s appetite for barrels eventually brought another 7mm cartridge into play – the 284 Winchester. This 50-year-old stalwart was revived a decade or so ago as the 6.5-284 and indeed this cartridge found some favor with F-Class pioneers – before the potency of the WSM was discovered. If you don’t mind shelling out for a couple of barrels per year (barrel life is about 750 rounds with the WSM) go for the 7mm WSM but, if you require a decent round-count, then opt for the .284 Win and learn to read the wind a bit better!

[Editor: In the last couple of years, another option has emerged — the 6.5 PRC necked up to 7mm. This wildcat 7-6.5 PRC offers a bit more velocity than a .284 Win or its “improved” cousin the .284 Shehane.]

Scopes for F-Class
If you will be shooting 1000 yards then I would recommend at least 32 power and preferably a variable – like the 8-32. The cheapest “usable” scope in this range is the Sightron. It’s a great scope for the money and at under $900 (in the USA) it’s half the price of its nearest competitor. It’s also light – at 1.5 lbs – and there are some great reticles for the F-Class shooter – like the LRMOA.

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.
