I am planning a camping trip and would like to bring a air rifle along to bag something for the pot. I can't really shoot a springer well and don't want to bring a a scuba tank along. I am thinking of getting a multi-stroke pump (I used my toy pump master once but i had to get within 10m for a clean kill, might as well use a springer) and am looking into buying a Cannon 737. Has anyone used one? How good is it? does the brass barrel last?
