Has anyone used this Sabot for longrange shots on Whitetals, say out to 150+yds or longer? I usually use the TC XTP Mag 240Gr. Sabots with no problems and they are devestating so Im keeping my first ACCURA set up with these and 150Gr. of Pyrodox.But Im setting up my newest CVA ACCURA for long range shots and the Barnes 250Gr. Spitfire TMZ's seem to be a good choice for flat shooting and prefromance in taking Deer Down. I prefer a magnum load of 3-pellets of Pyrodx, but Im looking for the best accuracy and flatter shooting.I will lighten the load down to 120 if I have to. Im also thinking of changing the powder pellets to the new Triple Seven Mag's any advice on this setup?
