Well shucks! I just returned from a wintry 150-mile round trip to get some BLACK BBs. The PC gurus insist on them being black, and who am I to quibble? I started PC-ing with BLACK and that's what has worked so well for me just as they instructed. So...........I have some new powder coming from a Forum Member here, and LO! No BBs!! Amazon.ca has some but there's a 30% 'shipping charge'. 'Local' store (15 miles away) has WHITE ones and other colors. Did anyone ever notice they're all different WEIGHTS?? The BLACK ones are the heaviest: depending on maker, 0.20 or 0.25 grams. The others are all mostly 0.12 grams weight. Obviously, the heavier BLACK BBs are the ones giving the better static charge which is maybe why some members here using 'colors' are not getting good results???
