Hello, I use 2 3/4" 20ga. Activ slugs for deer hunting and have for many years. The shoot relatively flat and are accurate. A couple years ago I purchased a rifle 12 ga. barrel for another of my shotguns, but have switched back to the 20ga. Funny thing is that I am shooting them from a Browning smoothbore pump with a vent rib barrel. I still shoot this better than I shoot that rifled barrel w/ sights. Give those slugs a try, I'll bet you will like them also.
