Commander IDS Plus 3-1/2″ 12 ga.
Here it is, the ONLY 3 1/2″ shotgun slug on the market! The Lighfield Commander IDS Plus was designed as the largest high velocity, extremely stable, extended range Sabot Slug for use in modern rifled or smooth bore barrel shotguns for very large game. The IDS 3 1/2″ Commander incorporates a 1 3/8 oz (600 grain) 73 caliber slug producing a whopping 4759 ft/lbs at the barrel and an insane 1327 ft/lbs @ 175 yards. TKO= 115! (Send in the elephants!) The patented IDS design incorporates an impact-discarding Sabot that aids stability in the wind and produces a controlled expansion slug for deeper penetration.
