Tite poop sure does a lot of damage with a double or triple charge. I don't use it for that reason. It doesn't fill up the case enough. I watch every loaded round and it's hard to see any powder in the case on my 650. I like a power that spills out on the shell plate with a double charge, not that I ever had one. I miss 7625. It was a very "forgiving" powder. You could double charge it, which completely fills up the case with some spillage, and just make major PF. Might jack up a Glock but not an STI!
