My elite shot the PB 245gr really well, I was using pyrodex P 110gr. Due to some fragmentation concerns I switched to 250gr bonded shockwaves. Mine load really easy with the superglide sabot that comes with the SW. I have never measured the bore of my rifle before so I cant say what the diameter of mine is. I am gonna try some of the crushed ribs, I read so much on here about them I just got to give them a try. I have only shot the PB and SW out of mine both with 110gr of P. Very tight groups at 100 yards with both bullets. I'm gonna do some playing around with mine when I get finished with bow hunting, just hadnt had time right now.
