When I was guiding I never knew what to expect but any hunter who was armed with a legal rifle for the game we were hunting was allowed to use it. At least for the first time I hunted with them. I liked to see a hunter show up with a well used rifle in 270 or 308. In most cases they knew how to shoot them. Of course there are exceptions no matter what they carry. I liked to have the chance to have them fire a shot or two at a target before we left to hunt. It was not always possible however. From my own hunting expierence the 270 was not a marginal elk rifle. I would hesitate to take on the polar bears with it but even they have been killed with the 270 and even a lot less. There is no game in NA that has not been taken with the model 94 30-30 and within its range it still does the job.
