Is it the actual powder that's responsible or poor loading practices? It's a dense powder so it doesn't fill the case as full as other powders and is very dark which can make it hard to see in the case. I see how that could make it easy for a distracted loader to double charge a case. It's my understanding that double charges are the reason for the KBs when using Titegroup. Do you know of other reasons?
