I used 777 and powerbelts last year, and now use 777 and 240gr. Nosler HD sabots. I was shooting the 245 powerbelt with the plastic tip, it shot good with 2 pellets, but we had a couple of powerbelts fall out of the barrel, and leave nothing but the green plastic base, so we quit using them. They are not suppose to come apart according to powerbelt, but all of the ones we had would come apart. They are easy to load, but that is not always good, if you notice most of the TV guys use sabots with the Encore. Of course most will shoot whatever is free to them, I just feel more secure with the sabot.
