Howdy 'Buster: I've run into the same problems with all the big name suppliers of RB lead. So, I go to Gander Mountain and buy the generic brand of RB lead for 5.99/100 for the .530. The next thing I do is weight out a group of 10 and find a more reoccuring wt in gr's. This has turned out to be 222.8gr. I use about +/- 1.5 gr increments as the RCBS powder scales swings above or below the "0" mark on the face of the scale. It takes about 30 min. to weigh 100 balls, but I check for roundness, dents, or bad shapes and end up with 5 bowls of mean weight and + 2x's and -2x's the 1.5 gr balls. It sounds tedious, but when you do 4-600 balls you can zero your gun and befairly sure of good percision for each group. I shoot these for leagues,woodswalks, and even Friendship championship matches. Save yourself the toxic fumes and possible cataracts and shop around. GOOD SHOOTIN and LUCK. :grin:
