Tactical Guru Ryan Cleckner on Gun Talk Radio this Sunday

Ryan Cleckner long rage tactical Tom Gresham Gun Talk

There’s a good episode of Gun Talk Radio this Sunday, 2/27/2022. This week’s lead guest is respected author and former U.S. Army sniper instructor Ryan Cleckner. Host Tom Gresham and Cleckner discuss hunting, long range shooting, and tactical training. Ryan Cleckner is the author of the best-selling Long Range Shooting Handbook.

This broadcast airs Sunday, February 27, 2022 from 2:00 PM to 5:00 PM Eastern time on 270+ radio stations nationwide. Listen on a radio station near you or via LIVE Streaming. This week you can also enter Gun Talk’s Good Guy Giveaway Contest.

Effective Rifle Training with Ryan Cleckner
Along with his written work, Ryan Cleckner has created many good shooting videos for the NSSF, such as his excellent Understanding MOA Video. He also produces content for GunUniversity.com. Ryan is noted for his ability to explain complex topics in an easy-to-comprehend manner. This video below, covering the fundamentals of shooting, has been viewed over 2.9 million times. It’s worth watching, particularly for guys getting started in PRS/practical competitions.

In this video, Ryan Cleckner reviews proper technique for rifle shooters. A stable platform, sight alignment, sight picture, and trigger control are key fundamentals to shooting properly.

Tip on Viewing Your Reticle:
Cleckner: “Sometimes it can be difficult to focus between the target and the reticle, even with the parallax adjusted properly. I recommend you focus only on the reticle. Just like the front sight on a rifle or a handgun, that reticle is what you can control, and it’s what matters. Focus on a crisp, clear reticle, in a stable platform, and all that’s left is trigger control.”

Tip on Trigger Control:
Cleckner: “Trigger control is pretty straightforward, as long as you think about it as a continuous process, and not just one thing that happens. I like to think about it as drawing a line in the dirt. I like to think about this constant pressure that I’m adding as I draw this line straight back, and then… continuing to draw that line even as the rifle goes off. That’s the good follow-through you’ll need.”

Long Range Shooting Handbook — A Good Resource

Ryan Cleckner’s Long Range Shooting Handbook is designed as an introduction to important fundamental concepts such as MOA vs. Mils, External Ballistics, and Environmental Effects. It also include advice on shooting positions, and gun handling. Included are personal tips and advice based on Cleckner’s years of experience as a sniper instructor and special operations sniper.

The Long Range Shooting Handbook is divided into three main categories: What It Is/How It Works, Fundamentals, and How to Use It. “What It Is/How It Works” covers equipment, terminology, and basic principles. “Fundamentals” covers the theory of long range shooting. “How to Use It” gives practical advice on implementing what you’ve learned, so you can progress as a skilled, long range shooter. You can view Sample Chapters from Ryan’s Book on Amazon.com.

Headspace — How to Measure This and Set Dies Accordingly

Do you know what the inside of a rifle chamber (and throat zone) really looks like? Do you understand the concept of headspace and why it’s important? If not, you should read the Brownells GunTech article Gauging Success — Minimum Headspace and Maximum COL. This article explains the basics of headspace and shows how to measure headspace (and length to lands) in your barrels with precision. The article also explains how to adjust your full-length sizing dies to “bump the shoulder” as needed.

Why is headspace important? The article explains: “Controlling headspace and setting proper C.O.L. also represent improved safety and reduced cost of handloading. Excessive headspace can cause case head separation and gases in excess of 60,000 PSI escaping from a rifle’s chamber. Too little headspace can result in a chamber forced bullet crimp and a bullet that becomes an obstruction more than a properly secured projectile. Excessive C.O.L. can result in a rifling-bound bullet, a condition that could result in spikes of excessive pressure.” [Editor’s NOTE: It is common for competitive benchrest shooters to seat bullets into the rifling. This can be done safely if you reduce your loads accordingly. With some bullets we often see best accuracy .010″ (or more) into the lands. However, this can generate more pressure than the same bullet seated .010″ away from initial lands contact. As with all reloading, start low and work up gradually.]

How is headspace specified? Most cartridges used within the United States are defined within ANSI/SAAMI Z299.3-4. Brownells explains: “In the case of the .243 Winchester, as an example, there are pressure specifications, cartridge drawings and, as pictured above, chamber drawings. Armed with a chamber drawing, each manufacturer producing a firearm for the .243 Winchester knows the proper standard dimension to cut chambers and set headspace. Notice there are two headspace reference dimensions for the chamber. The upper is a place in the chamber where the shoulder is .400″ in diameter; the “datum” or “basic” line. The lower is the 1.630″~1.640″ minimum – maximum dimension from the breech face (bolt face) to that point in the chamber that measures .400″.”

The actual headspace of any firearm is the distance from the breech face to the point in the chamber that is intended to prevent forward motion of a cartridge.

Finding Cartridge Length to Lands with OAL Gauge
Using a comparator on a set of calipers, you can quickly determine cartridge base-to-ogive length. This is the measurement from the base of the case to the forward-most full diameter section of the bullet, which is for convenience called the ogive. (Technically, the “ogive” is the full curve from bullet tip back to full-diameter ring). Shown here, that ogive is 0.243″ diameter.

The next step is using a modified (threaded) case with a Hornady OAL tool to determine Length-to-Lands (LTL) in your rifle’s chamber. During this measurement process, the modified case, with a bullet in its neck, is inserted in the chamber. Go slow, take your time. Here are 5 tips that will help you get repeatable and reliable LTL measurements:

1. Start with a clean chamber and clean barrel throat.
2. Make sure the modified case is fully screwed down and seated on the OAL Gauge. It can sometimes unscrew a bit during repeated measurements.
3. Insert the modified case slowly and gently, but ensure the shoulder of the modified case is fully seated on the end of the chamber.
4. Push the gray plastic rod GENTLY. It is common for the bullet to be tilted a bit. You want to allow the bullet to self-center in the throat BEFORE you apply much pressure. Then tap a couple times and push until you feel resistance. Do NOT push too hard — that will jam the bullet in the lands.
5. Repeat the measurement at least 3 more times. If you follow our instructions, you should, typically, get a repeatable measurement, within 0.0015″ or so, 3 out of 4 times.
