Quick Answer
Glass bedding is a worthwhile investment for hunting rifles, particularly for long-range shooting, as it offers improved accuracy and consistency by reducing rifle movement caused by recoil and temperature changes.
Understanding Rifle Movement
Rifle movement is a significant factor affecting accuracy. Every time the rifle recoils or heats up, it shifts its position slightly, which can result in group sizes that are far from ideal. Glass bedding helps to minimize this movement by creating a solid, rigid base for the rifle action, allowing it to maintain its position even under heavy recoil. For example, a well-bedded rifle can maintain its zero within 1-2 MOA after 20 rounds of 308 Winchester fired at a rate of 5 rounds per minute.
Installing Glass Bedding
Installing glass bedding requires precision and patience. The process involves carefully gluing a layer of glass or a similar material to the stock’s bedding area, ensuring a perfect fit for the rifle action. This can be done using a variety of techniques, including the use of a specialized jig or by applying a thin layer of bedding compound to the action and then using a press to secure it in place. A well-installed glass bedding job can last for many years and withstand the rigors of heavy hunting use.
Benefits for Long-Range Shooting
For long-range shooting, glass bedding is essential. It allows hunters to achieve groups that are tight enough to take advantage of the capabilities of their rifle. For example, a well-bedded 6.5 Creedmoor rifle can produce groups under 0.5 MOA at 100 yards, which is more than enough to take down game at ranges of 500 yards or more. With glass bedding, hunters can focus on other aspects of their shooting technique, such as sighting in their rifle and developing a consistent shooting form.
