02/17/2009 Update:
Shot the .675 Cabela's 3.5" DC T last night on a hunt.
Chose it over the .685 Undertaker because the UT said it was for "lead only".
Well, great first set...called 4 foxes in and a yote. Got shots at 3 of the foxes...missed one in brush at oh...35 yards. Missed another in the wide open at...wow...35-40 yards. And hit one at 30-35 yards in an open pocket of brush (i.e. a hole in the brush)...tracked it for 250-300 yards with no increasing blood...and never found it.
It's pretty sad, I feel like I'm shooting blanks out of this gun. In nearly 20 years of hunting, aside from predator hunting, I don't think I've missed that many animals combined with bow, shotgun, or rifle. And wounding one and not finding it is completely unacceptable.
Part of the problem could be using T for foxes...but with the chance of yotes in these areas, I'd prefer to use the T. The bigger problem is the patterns...the gaps and voids concerned me during patterning...and last night confirmed my concerns.
So...this gun is getting shipped back to Benelli for their review. It won't be taken back into the field again until it is shooting patterns I deem acceptable...if that happens.
