A repeater CAN add to your bag, but it's not necessarily so.
Many years ago I hunted with a couple of fellas I knew. They were both using pump 12 gauges, and I was using my old single shot 20 gauge.
They gave me a hard time about my little single shot on the way out to hunt, and I gave them a hard time on the way back. When all was said and done, Van ended up with 3, Steve had 4, and I had a limit of 15.
You just have to hit them the first shot.
I used to hunt with a 12 gauge Remington 1100, and it was great. I can remember taking 3 birds in three shots when a group got up. It happened many times.
Thing was, I got tired of limiting out early, and then having to wait for other folks to hunt all day to either get a limit or until it got dark.
I like my little single shot, and most times leave the repeaters at home.
