RE: Is this possible??? Switchback vs. Allegiance!
Jason,
To tell you the truth they BOTH look low speed wise…….I never trust those Techno Hunt screens for accurate speed ratings. (They’ll be pretty consistent shot to shot but the actual calibration could be way off) The shop I used to shoot at had one and the screen was 12-13fps SLOW vs their good shop chronograph.
The reason I say YOURS looks a little slow too is that I get 278fps with a full string load (peep, loop, 2 tied in nock sets and leeches) 30”/61# and 407gr arrows.
Backing off a 70# all the way to 61# accounts for some but not all of that difference between mine and yours.
I can believe the difference between the 2 bows as posted, especially given efficiency of the binary cams , but my impression is that both numbers are little low equally.
Truly measure each bows draw weight and shoot them through a reliable chrono………while you’re at it measure the actual AMO draw lengths for the 2, that should trip him out even worse.
