Barnett real speeds

christopher · Jul 11, 2023

How many have run your Barnett through a chrono? Just curios how close they are to advertised speed?

my findings:
Barnett Whitetaill Hunter II 350FPS advertised speed - 445 grain arrow real speed 332 FPS
Barnett TS370 / 370FPS advertised speed - same 445 grain arrow 352 FPS

I think they are pretty close to advertised speed with 400 grain arrow

Barnett XP 350 shoots s 400 gn 364 fps. Have had my TS 370 at 376 fps with cam advance.

Fixed: 352FPS

Previously posted: My Barnett Wildcat C5 had an initial velocity vs arrow weight curve described by:
Feet/ Sec = (-116.5 x ln Wt, gr) +1016. My heavy hunt-ready arrow weighed 565 gr. and chrono-ed at 275 vs 278 calculated. Barnett's advertised arrow speed is 324 fps. A 400 gr arrow is expected to launch at 318 fps.

Forgot to run a 380 gr arrow. With the same formula the lighter arrow clocks as advertised at 323.9 fps.

My TS380 chrono'ed at 386 after new strings and tuning, using the arrows that came with the bow.

TS380 is a fantastic xbow. Great speeds on that setup.

386 with 400 gn arrows is 10 fps faster than I have ever seen on a TS. That is a good tune job.
