Being a bit recoil shy, I prefer sabots over big lead. Unfortunately, Idaho requires all lead, full caliber for ML. Also, some guys here have achieved phenomenal accuracy with big lead, but not wanting to go over 435 grains, I have yet to crack that code. When hunting in Oklahoma, my 54 cal MK-85 produces minute of angle groups with any of the half dozen sabots I've tried. Easy. I've settled on 260 grain, as being big enough to do the job. And with 90 grains (by volume) of Pyrodex producing the best groups, its a pleasure to shoot. For ease of getting good accuracy, I'd recommend sabots. Unless you are going for elk, like Idaholewis. Then, I'd say bigger is better, and recoil is part of the game.
