I would recommend the Mick Lacey Chinook to start out. Its a cheap call to learn on, and it breaks over very easy for a beginner. Although I have several nicer calls, I still use this as one of my finisher calls, because it makes great moans and murmers.

For a more expensive call, and if you dont have a problem supporting the company, the foiles strait meat honker is a greta beginner call. very little back pressure required.

For loads it is important to pattern your gun and know what Choke/Loads work well out of your particular setup. For me in my Browning Cynergy I use Carlson IM in the Top Barrel and Carlson LF in the Bottom Barrel with Hevi Shot Speed Ball 3 inch BB. That setup allows for shooting from 13 - 51 yards and 20 - 64 yards with a good pattern. Last year I used Black Cloud BB but had several failures and have switched this year. That Combination worked well this last weekend.

In my Benelli SBE II, I use Briley WaterFowl Long Range for Long Shots with 3inch HeviMetal BB and I am good out to 67 yards but any thing under 23 is a crap shoot. If the shoots are closer I switch to Carlson IM with the HeviMetal BB and can do well from 14 yards out to 53 yards. My gun also patterns 3 inch HeviMetal Number 2s and can actually extend the useful pattern out to 71 yards but that is really pushing it...

Best advise is to get you a couple of boxes of shells and some cardboard. Go out and pattern your chokes/loads. Use that data to make the decision on what you think is best for your setup.
