I'm shooting a Matthews Monster MR8 @ 70lbs. I think the IBO speed was 300fps, so I used that to do the calculations. It seems to be relatively flat shooting, but like I said I haven't ever chrono'd it before.
I'm planning on heading in there labor day weekend for about 4 days. Although there are murmurs about an exercise rotation happening in September, in which case I will be very very upset and have to find a general season rifle to hunt in October...
