You will have to define what you mean by "better". All are more accurate than you are likely to be. In other words, unless you are a bench rest shooter or a chunk gun shooter who are looking for one hole groups, you will never be able to tell the difrerence in the accuracy of one barrel over the other. However, if by better, you mean which one has the better rifling or outside finish, you will be hard pressed to find a barrel that is better in those respects than a Colerain or Rice barrel. But, if Green Mountain is one of the choices and you happen to prefer it or can get a better price on it, you won't go wrong in buying it. Today's barrels are all better than most shooters. I have several different barrels and all will shoot better than I can. Pick the one that has the more desired features that you like such as the type of rifling that you want, the twist rate that you want or the best price and you will be happy with your choice. :thumbsup: Having said that, if I were in the market for a new barrel, I'd be buying a Rice barrel because I like the rifling and the finish of the bore (polished) is better than you will find elsewhere. Just my opinion.
