Rifle bedding is an essential detail of a rifles accuracy. A correctly bedded rifle has greater accuracy and consistency leading to greater success.
Bedding a rifle corrects the relationship between the rifles action and the rifles stock and creates a precision fit between the 2 components.
The precision fit means that firing stresses from the barrel traveling through to the action are managed far more naturally and repeatably by the stock.
A correctly bedded rifle removes movement between the action and stock when the firing pressures are stressing the assembly and this is vital for consistency.
