That's about the worst thing that you could do. The salesman's job is to make money for the store. He may not know anymore than you do. If he is a good salesman, it is possible that he will sell you the items in stock that have the best profit margin. Get a "ABC's of Pistol / handgun re-loading" book at wherever you can find it and it will pay off handsomely in knowledge received. And go visit your friend that re-loads.
