My preference is more to open chokes , IC / mod are about as good as it Getz however for an all around upland SXS it O/U
My favourite gun however us CYL/CYL , over the dogs I have never had an issue killing anything from grouse to wild pheasants if the birds are holding .
If they are getting up 50 yards away however , it's a crap shoot no matter WHAT you are using !!
