Just to chime in on an older thread.
My H&R shot the Lightfields best (1.25 five shots @ 100yds), but I was having to pass alot of shots due to range. I switched to SST's which gave me 1.5 @ 100yds. I could cover both at 200 yds with my hand (about 3-3.5").
I have shot and killed deer with both and have not had any problems yet with killing power. My wife calls the gun the "Meat Bringer" and my in-laws call it the "Sniper Shotgun"
My average killing distance with the LightFields was around 100yds with 22 deer down. My average with the SST's is 140yds with 39 deer down. I have killed as far as 226yds with it (went through a little deer from front and exited just infront of the hip). Last weekend I dropped 3 with it 128, 137, and 186 yards.
I'd say this gun and the SST's are just fine. However, tomorrow I get to go help a friend with his as he says he can't get it to hit right. Since he bought it on my recomendation, I will figure it out for him and we will be hunting tomorrow evening. I only have one tag left, but he has 6 to fill.
