i tryed middle bedding, center bedding. But none of these methods is better than military barrel bedding . If you're lucky one barrel bedding pattern leads to the same - good- results. Middle bedding and center bedding would be user friendly if you use a sling to shoot, a very tensioned sling. Because i shoot from a front rest i prefer to use military bedding obtaining good accuracy. But military bedding is good if you use a sling also. So...do not deviate from kosher.
For 2 years a tested on range with the same round different barrel bedding. Today 2 years means " the Infinity" ... but think: No.4 rifle has been produced in millions , many armourers tried, examineted and shot it. In different Countries. Probably they gained much experience in 20 years service than now today we could gain testing our rifle at our local range. So, do not deviate from approved bedding method as a rule of thumb.
