If I use a fire arm this year, it will be a 12ga with Sabot slugs. I shoot remington 870, open sights with slug barrel spitting Remington Premier AccuTip Sabots. Usually the 3", which is 385 grains traveling at 1900 fps.
When I get a rifle tag agian in ND, it will be my Tikka T3 in .308. I haven't shot in a while, can't remember which rounds worked the best.
