I use this as a pest control weapon and basement practice. The Crosman was easy to site and ammo is very cheap and diverse. There is some noise, but otherwise it is very quiet in comparison to powder. It is a bit heavy at 6lbs, but much more accurate than the pistol. This is very good for small game. Larger game in a survival situation would ultimately be wasted by spoilage. I like it and would recommend it. 250 pellets come in a chew size container.
