the ONLY reason I run N500s is to boost speeds of things like 90 jlks in competition matches... if I were not shooting to win, I'd be leaning back towards TAC or others generally, as N500 isn't cheap, hard to get sometimes etc... but it does shine for what I use it for.
Just FYI. AND it won't like anything but warm to hot loads generally speaking. I was told that and still started low and was pissed with the groups, but once we got to the max charge area things shrunk and I've won more than a few things going that route match wise, including some nice results in national ocmpetition
