Saturday at the Movies: Great Tech Advice from Keith Glasscock
Keith Glasscock is one of America’s greatest F-Class shooters, as well as a highly respected wind coach. A High Master, Keith finished second overall at the 2021 NRA F-Class Long Range Championship in F-Open division. He also finished second at the 2020 Nationals, tied with F-Open winner Pat Scully on points, but with fewer Xs. And he took second also at the 2019 Nationals. His consistency is unrivaled, which means he definitely knows the secrets of long range wind calling and loading ultra-accurate ammo.
Keith has a popular YouTube Channel with new content every week. On Keith’s Winning in the Wind channel, Keith offers 60+ informative videos on a wide range of topics including wind reading, reloading, component selection, load development, and training. For today’s Video Showcase, we offer four of our favorite Keith Glasscock videos. Each video has important points that can benefit any competitive rifle shooter, whether you shoot in local 100-yard fun matches or compete at the National Level in F-Class, LR Benchrest, Palma, or High Power.
How to Prepare for a Match
In this informative video, Keith explains how to prepare for a major medium- or long-range rifle competition, with a particular focus on F-Class. Keith explains how to prepare for weather conditions and “get the lay of the land” before the match. Even the day of the match, your can look and learn. As one viewer noted: “I’ve noticed some guys playing on their phones during matches. This is an important time to get in sync with wind patterns and fine tune your wind strategy.”
How to Find (and Fine-Tune) Seating Depth
This is Keith’s most popular video. Keith definitely knows how to maximize accuracy by finding the optimal seating depth for each particular barrel. He is achieving groups in the high Ones for three shots. That would be good for a short-range benchrest cartridge, but Keith is achieving that with a .284 Winchester which has much more recoil. If you shoot F-TR or F-Open or even PRS, you should watch this video.
How to Lower your ES/SD and Reduce Vertical at Long Range
This is Keith’s first video in a series on how to improve long range groups, precision, and accuracy by reducing velocity Extreme Spread (ES) and Standard Deviation (SD). To achieve the lowest ES you need to look at multiple processes, including precision powder weighing, careful seating, brass annealing, and primer selection. Another factor is bullet selection. Not all bullets of the same nominal caliber and weight class have exactly the same bullet diameter or shape. Sometimes you can get better accuracy AND lower ES by trying a different brand of bullet. We have found bullet diameters, of the same stated caliber, can vary by up to .0008″ (eight ten-thousandths). Some barrels like the fatter bullets, while other barrels may favor the skinny bullets.
How to Find Bullet-to-Rifling Touch Point
Before you even start to load for a new rifle you need to know the point at which the bullet in a loaded round will first touch the rifling. (This will be a base to ogive measurement on your round). Beyond that point you are “in the lands”. If you load shorter than that base-to-ogive length you are “jumping” your bullets. Some cartridge/bullet combos typically shoot best in the lands, while with other bullets and cartridges, jumping is the way to go. Additionally, with some disciplines it is wise to jump your bullets since you may have to unload a chambered round while on the firing line. In this video Keith shows a number of methods to determine “length to lands” with repeatable precision.
Field Test and Review of SEB Mini-X Coaxial Front Rest
While gear reviews are not the primary focus of Keith’s YouTube Channel, Keith does talk about products he likes and uses. In this video. Keith reviews the SEB Mini-X, the newest coaxial tripod rest from SEB Rests. The Mini-X offers fast, precise windage and elevation adjustment with the joystick control. The unit is much easier to pack and transport than a large, heavy front rest such as a SEB NEO or Farley. The latest Mini-X also has upgraded foot controls that make it easier to level the rest on uneven ground. For more info, see our SEB Mini-X Report.
