Yesterday I took my Benelli M4 to the range to try some distance shooting using slugs. This Benelli has a 14 inch barrel and iron sights, so I didn't expect to be able to hit much, but I ended up being pleasantly suprised. I also don't have much experience using iron sights because all my AR's have dot sights or scopes. To make maters worse, there was a gusty 20 MPH wind at the range. First I rapid fired 12 - 3" magnium slugs at 50 yards - without trying very hard to aim - which gave me a mild headache and resulted in plenty of hits - (2 liter water bottles).
I was also able to consistantly shoot (2 liter) water bottles at 100 yards with reduced recoil slugs and factory irons while standing.
Lastly, I tried to shoot some 24" X 18" steel plates at 200 yards using irons. At this point all I had left were (3) 3" magnum slugs. Dispite the wind and the fact that I was flinching quite a bit, I hit the steel plates 2 out of 3 times. I think luck was a big part of me hitting the targets because of how bad I was flinching and how small the targets appeared in my iron sights. This caused the 1/4" steel plates to be dented maybe about 1/8"
