I use a Mossberg cantilever 20 gauge, 2 3/4 Lightfields, Simmons Prohunter 3x9x40 Prodiamond scope. Hits 2 inchs high at 50 yards. I have picked off more than one deer through little holes in the thick stuff at 9 power. Longest shot was approx 70 yards.
I use a old Mossberg 500 that was my Dads from the early 70's. I just bought a new 12 gauge cantilever rifled and ported barrel from Cabelas. I also use a Simmons 1.5x5 Pro Diamond scope with Lightfield 2-3/4" sabots.
