I have acutally sold the high grade KSC .20 and .25g for the past couple of years now, and not once, have I ever heard of any kind of problem either from the 1000's of bags to customers sold, or even our own club members who use them. Also, the ones I have come with 4000 rds/bag, so you get a little more too. Never personally done testing on BB's, but I have never had a problem! If your into testing BB quality there mcguyver, then drop me a PM. I will send you a bag of my KSC for you to run some tests on. I would be curious as to how they stand up to others you have tested!
