Haven't tried Longshot, I'm more or less addicted to Green Dot and HS7. (In heavy loads, HS7 produces a higher velocity at lower pressures than Longshot). Buffered loads scare the crap out of me. Seen one fixed-choke (Full) gun with the end peeled. Don't know what the load was or what buffer was used, but something obviously was wrong. I've heard too many negatives about buffers for me to try it.
Just my .02.
