Hello everyone, I have a five and a half inch 44 special bisley custom with a pacnor barrel by David Clements. It shoots 7.5 grains of unique and a 250 grain lead head bullet accurately, however I do get leading just in front of the forcing cone. I talked to David and he said to try matts bullets at bhn 11 and 4227. With the 4227 and that bullet I got no leading but not near as accurate. David said some guns will lead with unique. David also said the gun will not leave the shop without proper dimensions so that is not the problem. The 4227 load was 16 grains, again clean no leading but not near as accurate. I sure would like to use the unique load with no leading or something that shoots just as good with the 250 grain bullet and same performance. Any help would be very much appreciated. I also have 2400 but I dont want much over 1000 fps. Thanks guys
