I bought a slug of them cheap and in my steel shot loads for my 12 ga, they are working flawlessly. In fact, an alliant rep told me to compare them to Win 209s. In my handguns they seem to be as good as any. Now... I just shot some 7.62x39s the other day with reduced loads for cast bullets and they seemed a bit cooler than the CCIs. In fact, some of them seemed downright anemic! I definitely am not writing them off, as the price is right.
I would suggest you give them a try. Thing with reduced loads,is it is very possible that the powder I was using is position sensitive and that could very well explain why just a few seemed weak.
