I've shot a lot of shotgun shells in my life, but have never hunted big game with a scattergun (though I've always wanted to).

What brand of barrel/choke are you using if you don't mind me asking? 4" group at 50 yards is phenomenal.

I used to chat with Stan Baker at his shop in Lake City (or was it Kenmore) back in early 90's. He was quite instrumental early on in the development of choke tubes. I always did want to own one of his barrels, but at that time in my life, they were priced out of my reach.

Good luck! Off to cut up my kids Idaho whitetail.
