If you're asking me if I think I'll break 500 with my planned mods.... probably not, at least from what I've seen, but I'll be running stock DV's and I haven't had my barrels racked. But then again I'm just guessing and I'm not expert.
I would think with the .022's you'll be over 500, but I highly doubt you'll see 600 if that's what you're after, at least not on fuel only, but I could be wrong.
