20 ga. Remington 870
I had a chance to pick up a slightly used Remington 870 with extended magazine. So I bought it, and took it to the range. I have to say, I love the way the 20 ga. handles. Very easy on the shoulder, and amazingly accurate. I shot slugs at 75 feet, and grouped 10 shots within 5" of center target. Incredible considering it has bead rear sight only. I always believed it was 12 ga. or nothing, but I really enjoy this shotgun. Much easier on my old body. I'm hooked.
