270 win.

I have a sporting over-under that i use for trap...There are features I would like to be different but I got what I paid for. If this one wears out out i will go get another one.

Just for information mine came from Biakal, Russia - they made the infamous AK-47 and several other guns. They are not ametures at producing a gun that will keep shooting for along time. They certainly do not have the quality of Browning and such but they work.
