Those numbers do seem pretty low. Did you draw the 10" circle around the densest part of the pattern after shooting or did ya draw the circle then shoot? Could be the choke constriction is too tight, but it could be the barrel needs really scrubbed out good and be free of oil. Cold temps will give you lower numbers also. I haven't shot either one of those shells so I can't give you any 10" counts for them, but I'm guessing with the mag-blends you should be in 250 range at least.I know I've seen a few posts somewhere that guys were getting over 300 with the blends, so something is definitely off.
