ive been getting much help here about my drilling and am starting to recieve the goodies to make her sing.. i just got hulls, hull cutter, loading data, roll crimper, overshot cards, from a major shotgun shooting supplier. they were very good about supplying extra info and was helpfull in getting started.. i patterned about 20 rounds with varying loads useing local gunpowder to get around hazmat.. the problem is the best pattern im getting is around 40 percent,modified choke,,,most are much worse.. the westley richards shells that someone gave me to try gets 60 percent average with same shot, distance, choke, circle diameter.. have any of you used the roll crimped with success?.. a competetor of the company questions the roll crimp drill attachment and the load data of thier competition.. anywhay im about to buy a mec 600 junior with short kit in hopes it will cure the problem,, any advice on this??? thanks dave..
