A buddy of mine won an 835 ulti-mag at a banquet last year, and has just taken it out of the box 2 days ago. Tried to pattern the gun and he has to aim a foot high, and a foot to the left to get bb's in the target at all. He has tried several choke/load combonations, and all with the same results. Anyone else having problems like this with their 835 ulti-mags? Any suggestions to what the problem may be?
