RE: 10 Gauge pros and cons..?
I have a 870 3 1/2 and my friend hunter has a NEF 10 gauge with a modified and we hunt deer alot and heblew one to ground meat but if you get the right combination for your 12 gauge then i would go witthe 12.
I love my 870 with a super full for everything and i would throw that POS 10 gauge in the river but its up to you
