I am thinking of buying a M1 Field 20 ga. in Advantage Timber HD for duck hunting (with steel and Kent Tungsten Martrix) and small game / upland hunting. I'm curious to hear from current owners of this shotgun. Have you used it in these hunting situations? What do you think of the durability of the camo finish? Plus your overall impressions of this shotgun. I currently duck hunt with a Rem 11-87 SP 12ga., but would like to add a versatile 20ga. to my collection. Please advise.
