Ok, Im contemplating getting a new barrell for my dads mossy 835.. For whatever reason, the patterns are not even close to being similar... Was out a few days ago patterning our turk guns and shot 4 times, same choke, same shells... One would be right on the money, one "decent" and then 2 way off, one to the low left and one high right.. And also the pattern itsself is not tight at all, pellets straying all over everywhere.. Going to have him shoot it 4 more times and see if it continues to happen.. If it does continue to happen, should we chalk it up to a bad box of shells.. or could it be more of a serious problem, possibly with the barrell? The shells in question are Frederal Premium 3.5" #6's 2 oz shot, the new ones with the flite control wad.. I can understand the gun not liking the shells, but why 1 time awesome.. 1 time iffy and 2 that wouldnt even faze the turk??
