[QUOTE="Carlos88, post: 2167397, member: 116554"] Here's how to do it on the cheap. Can't afford match dies anymore so decided to fix runout on some standard Redding two die set for my 7x57. Took awhile because runout was just horrible (130gr Interlocks). After numerous attempts found a dummy with the 139s that I measured at. 001. Removed the seating stem and placed it in a soft jaw wise. Grabbed drill and 1/8" bit and drilled a pocket at the bottom of the stem 1/16" deep or so. Scratched the side of the cup. Clean the whole mess with alcohol. Mixed up a dab of Acraglas (green/blue box). Took a toothpick filled the pocket and sides with a small amount. About size of an eraser head worth. IMPORTANT: Spray the dummy round with Hornady One Shot case lube. Then do it again and let it dry. Spray inside of the die as well. DON'T SPRAY THE STEM. Screw stem back in, screw die into press, place the dummy round in the shell holder and raise the ram. Feels like a little squishy. Let the weight of the arm do the squishing. Don't stand on it! Let dry for at least 4 hours. Lower ram. Remove stem then clean up around cup with a small metal file. You just bedded your seating die. Yes, it works, albeit with only 139s but they're meat and potatoes for a 7x57. It doesn't make a match grade die but it will consistently get it in the .003" or less. Caveat: I only shoot hunting rifles. One or two custom barrels, the others all factory. None over 8 1/4lbs. I also bed my AR15 uppers and lowest. What do I know. Hope it helps someone. [/QUOTE]
