If you have a scoped rifle with a barrel less than 30" long,the scope will bottom in the case before the barrel.If the case is mounted with the barrel lower than the butt(as is usually the case),the scope will support the guns weight,and take all of the abuse from riding over rough terrain.I have seen two scopes actually damaged from this,and many more knocked off of zero.If you insist on using a Kolpin Gun Boot,stuff the barrel channel with material until the barrel bottoms before the scope.
