For some reason I like the pump the best. O/U and semi's didn't make it enough of a challenge with having to cycle the round in time to get the second clay.. One day I'll pick up a nicer shotgun.
Yeah for me it was an accuracy thing. I actually preferred shooting an old Sears-Robuck single shot 12 gauge break action to the 870 because I was better with it (even though the 870 is a MUCH better gun)... So far with this Citori field gun I'm hitting a lot more than I ever have before. I think my best round so far is 18/25 birds! (which is actually horrible for those that don't shoot)
The only way I justified getting the 3rd shotgun is by selling my first rifle (a Tikka T3 22-250 w/scope and bipod) and my handgun (a SIG P226 .40)... I just find I have more fun shooting at a moving target than paper!
