Once again I am going to reveal how much I don't know yet about African hunting, but, as my old teacher used to say, the only stupid question is the one you don't ask. A lot of safari rifles, especially in large calibers, either come with barrel bands for the front swivel, or people write that they have upgraded to one. What is the point? Why is a barrel band preferable over a swivel in the forestock? Any advice will be appreciated.
