Quick Answer
Pressure points in bedding can cause rifle movement, affecting accuracy. This movement is usually due to the rifle's weight and the uneven pressure distribution on the bedding material. As a result, the rifle's scope may shift, leading to poor shot placement.
Understanding Pressure Points
Pressure points occur when the rifle’s weight is concentrated on specific areas of the bedding material, causing it to deform and create uneven pressure distribution. This can be due to the rifle’s design, the type of bedding material used, or the way the rifle is installed in its stock.
Identifying Pressure Points
To identify pressure points, look for areas where the bedding material is compressed or deformed, such as around the recoil lug, action screws, or barrel. These areas can be prone to creating pressure points, especially if the bedding material is not designed to accommodate the rifle’s weight distribution. For example, a rifle with a heavy barrel may require a thicker bedding material to prevent pressure points from forming.
Minimizing Pressure Points
To minimize pressure points, use a bedding material that is designed to accommodate the rifle’s weight distribution. For example, a material with a high compression modulus, such as polyurethane foam, can help distribute the rifle’s weight evenly. Additionally, consider using a rifle with a lighter barrel or a stock design that allows for better weight distribution. In some cases, installing a recoil lug or using action screws with a longer thread length can help reduce pressure points and improve rifle accuracy.
