That's a good question. I spent yesterday going through our Reloading Guide and asking our ballistics guru and it depends on which barrel you’re talking about. On some cartridges a 26" barrel may make sense to some competition or long range shooters. On other barrels that's what we had on hand, and they shot well, so we didn't want to change anything on it. I hope this helps you make some sense of why we have 26" barrels.
