500Nitro,

I must apologize to you and everyone else. I mispoke in my previous post, memory seems to be going, I checked the notes last night and the velocity difference is actually 30 to 40 fps (not the previously erroneously stated 15-20). I can get ~ 40 fps increase with IMR4350 and an ~ 30 fps with IMR4064 with the 500 AHR over a 500 Jeffery. Still an insignificant differential in the realm of reality.

Note to self, stop relying on the old memory!
