My 1100 consistently shoots low and to the right.So I'm looking for ideas to improve POI without resorting to an adjustable stock or having the barrel bent. Unfortunately it doesn't appear shims are available for this gun/stock combo.Cheek EEZ pads seem like a nice simple solution for raising the comb.However some reviews seem to suggest the adhesive is not aggressive enough to stay on synthetic stocks.Is there a rough rule of thumb in regards how much comb adjustment is needed for a particular amount of correction.Or is it all trial and error?
