I shoot the Encore in 45 cal and use a T/C Super 45 XR sabot. The XR's use a Hornady XTP 155gr 40cal pistol bullet. I push it with 100gr of 777 and get great results(sub-inch) with this combo in my particular rifle. As with any rifle, you'll have to try some different load combos and see which one gives you the best results. Good shootin'!!
