I've read that Ruger's new trapgun has 6 straight lands and grooves to keep the wad from rotating thereby improving pattern. Hastings now offer aftermarket barrels with the same sort of setup. Is it really worth it? Does it have to be done on an overbored barrel? Does it affect pressure? Works with any wad? I've bought a new 11-87 and had trigger work done on it, forcing cone lengthen, ported. Should I add this to the gun? Thanks.
