I have the 20 gauge model mounted with a Nikon 3X9 scope. The recoil is definitely less than a 12. I tested mine with five different brands of sabot slugs. All shot into less than two inches at 100 yards, but the Remington Buckhammer load and the Winchester Supreme grouped into an inch or slightly less. I have used the gun to take three deer at ranges from 30 yards out to 90 yards. All were one shot kills, with the deer not traveling more than 20 yards. Two dropped in their tracks. I have killed over 40 deer with 12 gauge slugs here in Illinois, but saw little difference in the wound channel/tissue destruction compared to the 20 with these two loads. I used the Winchester Supreme on two of the deer, and the Buckhammer on the third. I would not hesitate to use the 20 on deer with the modern sabot slug loads available.
