I've had a 4 screw M48 for years. It's a nice gun, put together well. I can't remember the last time I fired it. Ammo costs too much for what you get, in my opinion. I took it out years ago for some snowshoe rabbit hunting. It didn't kill as well as the K38 I usually used with cast wadcutters and 3gr of Bullseye. The K38 reloads cost about a penny and a half apiece then, while the 22 mag ammo was 6 bucks a box even back then. The choice was clear.
