For me, 90 grains of 777 ffg, vari-flame ignition (CCI small rifle primers), MMP 3-petal sabots, and Hornady .45 cal 300 grain XTP's work well in my Encore. It took awhile to arrive at this as I experimented with a variety of different components. I'm not sure that any one component 'did the trick', but as stated, this is what works for me on paper. In honesty, I only tried 777 pellets and AP fffg powder before switching to 777 ffg. No crud ring with the vari-flame ignition, BTW.
