I was shooting this last weekend and found something interesting. Wehn the sabot opened all four petals evenly, I was dead-nuts on. When only 3 of the 4 opened up, my bullet flew into the upper left quadrant. Up to 8" out. Ran a few checks, and turns out if the 4 petals weren't looking equally spaced when the round is started down the bore, only 3 of the petals opened up and I get a flyer out of it. This was only with my plinker rounds, the knight all-lead bullets and "soft" black sabots. My T/C sabots seem to be a little stiffer, and the petals didn't seem to have the tendancy to get "off center" when the bullet/sabot combo was started.
