same thing happened to me, can't remenber how i put gun together but it fits me real well and i shoot it very good.
my best guessis the R will give a slight right to the cast and a L will give a slight left cast. The hole orientation up will lower the drop slightly and the hole orientation down will bring the drop up slightly????
Okay boys, i just came into a chunk of money, so i ordered a Benelli Performance shop SBE II turkey special, it will take 6-8 weeks but be here for turkey season.
Gooble - boom! OH YEA.
I agree with mudhen i've patterned jellyhead and rhino both pattern very well with winchester xtended range.
I use the rhino, i figured since i spent the extra bucks to go ahead and use it.
just thought i'd let you all know my benelli vinci has one tom turkey notch on it. i'm a big benelli fan, bought my vinci 2 weeks ago, bagged it's first turkey a week later.
