302 fps, just like Brian from GA says
Brian from GA said:
I have not run this on AA but just looking at the numbers you are 1" short on draw length so you will lose about 10 fps there and your arrow is 35 grains heavier than IBO which is 350 grs so that is another 11 or 12 fps loss. You will lose a couple fps for a peep, d-loop, nocking point, etc so lets guess a 3 fps loss. With what you have given I would guess you will get between 295 and 300 fps out of this bow as described. I spoke with a coupl guys at the Buckmaster last week that have the Prestige and they are raving about it. Hope you like it.
OnTarget2! says 302 fps
assuming a d-loop,
The arrow is a bit on the weak side,
Easton Axis 400 cut at 26"
and with four 2" Blazers.
You can add an arrow wrap,
drop down to 85 grain broadheads instead of 100 grains,
and drop the draw weight to 68 lbs,
and then the arrow stiffness would be more appropriate,
and the estimated velocity = 300 fps
Mathews Prestige at 70 lbs DW
28" Draw Length
Easton Axis 400 shaft
Cut shaft to 26"
(not including the nock or insert length)
Use four 2-inch Blazer vanes
Use a full sheet arrow wrap (10 grains)
Use 85 grain broadheads
Assumes 15 grain peep sight
Assumes 7 grain d-loop
Assumes 7 grain tied nocking point
Assumes zero string silencers
Estimated Velocity = 300 fps
5.584 grains per lb of draw weight
FOC = 7.50%
75.80 lbs of kinetic energy
