For bears I carry a customized 480 Ruger revolver, so it can't be used to take a grouse or rabbit for a variety of reasons. The little 317 is light weight, carries 8 rounds, fully loaded with a CT grip weighs 13 ounces, and is accurate enough if I do my part. The only problem is the noise. Not terrible mind you with CB ammo, but it's definitely louder than I want. Maybe there is no better option? That's why this little rifle was so intriguing when I saw a writeup about it. The report/noise from a rifle barrel firing CB ammo is less (I think) than the best suppressed semi-auto 22LR pistol firing high-velocity ammo. A single shot is all I need for my intended purpose. Just looking at it online and having never held one, the durability of the pack rifle is my biggest concern. That's why I was hoping to find someone who owns one to comment.
