The Deerhunter has shallower grooves than the T/C traditionals so lighter sabots generally shoot well to 100 yards. Mine likes the Precision Sabot/Bullets best. I'm shooting 3" groups at 100 yards with 40/50 240 grain QTs or Dead Centers. My Deerhunter shoots 295 grain Powerbelts just as well. The cheapest place for Powerbelts is Midsouth.com. Here's the link for the Precisions.
