Bowflex- I too live in a state(NJ) where we must shoot slugs for deer and bear.
My slug gun is an older Rem. 870 WM whic I converted to a permanant slug gun. 24" hastings rifled bbl, 3x9 Burris sits on top and stock replaced with synthetic.
For years I shot the Lightfields. Excellent accuracy on paper @100yds and I killed deer. Found all my slugs inside the deer, most broken in pieces. Some deer required a followup shot. This season I tried the Hornady SST's, 12ga 2 3/4"(saboted). The accuracy was AWSOME!! Better than the Lightfield. I killed a 6pt at 66yds(rangefinder). The slug entered mid ribs and went out with a nice exit wound. The deer literally flipped over! The exit wound was testimony to the expansion of that slug. Second deer was a doe at 45 yds quartering towards me. Entered the between the shoulder/low neck region and went to the offside hip! Broke that hip too! Imagine going all the way through the lungs, liver, gut, ham and finally the hip. I'm sold on these SST's and amselling 6 boxes of Lightfields cheap. $5 a box! Want 'em?
