Hi

I went to the chronograph yesteray to see the speed I got with my new Firecat tr2.
I got 275 fps with my 360gr. arrow(goldtip ultralight400 + 100 gr.+ quickspin vanes) at 57 lb. exactly.

than, I shot a Beman Ics400 400 gr. and got 260fps.
So KE is the same with both arrows.
How much speed do you get with you hunting setup ??
I will hunt probably with my goldtip this year

Arrow placed properly either of your arrows will get the job done, but most would opt for the heavier arrow.

My hunting rigs gets 270 fps with a 380 gr arrow at 67 pounds, but considering lowering the draw weight. 60 will get the same results, deer in the freezer.

with my z at 30" draw 71# im getting 316 fps with a 395 grain arrow and it quiet is the best part

I hate you long monkey armed goonies. 30" Indeed!!!!!

Will, you're doing just fine with that setup for hunting. What's your draw length? If you are the typical eastern whitetail hunter then either arrow will be just fine. The difference in speed between them should only be about 1" or 1 1/2" at 30 yards so trajectory shouldn't be an issue.

If you are hunting out west and may get some longer shots then I'd go for the speed arrow.

Frankly, one of the best things that has happened to me recently is that my chrono crapped out so I don't know what my FireCat is shooting, nor do I care. Pretty much any properly spined arrow from a bow drawing 50# or more is quite adequate for deer sized game

Take it from me. shooting compounds for 37 years now and hunting was a lot more fun before we started worrying about how much speed and kinetic energy we had. We didn't know either nor did it matter. The results were always, as Sonny so eloquently put it, "deer in the freezer".

You're true :D

By the way, I shoot 29" and hunt moose and deer hunting in my own land in Quebec,canada.

Bows set-up per signature
'96 Firecat: Beman ICSH 340, 30.25", 3-4" vanes, 125gr pt = 465gr @ 245fps
'09 Bengal: PSE X-Weave 300, 29.0", 3-4" vanes, 100gr pt = 399gr @ 274fps
(probably going back to slightly heavier/higher FOC balance arrow for +/-415gr arrow @ +/-270fps)

I ran both above set-ups thru a ballistic simulation a while back.......input estimated range to animal was 40yds, with actual range being 45yds.
5yd error in range w/faster Bengal was 4.94" low of bullseye
5yd error in range w/slower Firecat was 6.33" low of bullseye
Heavier, almost 30fps slower arrow, calc'd that it missed by a whoppin' 1.39" more at 45yds
The old Firecat using a simlar weight Beman arrow w/Cabela 125gr broadhead, blew right thru a 3x4 mulie buck at that range

Not bad although I would have expected more drop at 45 yards. Must be that the heavier arrow retains a greater percentage of it's initial velocity down range. 1.4" ain't enough to be concerned about. Heck, I can't even hold that well on a target at 45 yards.

yeah, I'm sure not Robin Hooding arrows or consistently "X" ringing 3D targets out there at 40-45yds

The heavier arrow does retain a little more speed, but difference in change was less than 5fps in those examples.
Even when I took the same 399gr arrow and manually bumped calc'd speed 40fps from 274 to 314, it was still only 1.3" less error

I just got my TR1 and will finish setting it up tomorrow. I hope to goodness I get more speed than what I am hearing. I will be shooting about 370 grains at 70 lbs with 28 0r 29 draw. Will be disappointed if it is slow.

Guess it will depend on your definition of slow......if you're expecting well over 300, you probably will be.
My "guess"? 280-285 (28"), 290-295 (29")

Well, little disappointed. Shooting lightest arrow, Maxima, I can get away with and getting 294 if the Chrono is right. It does shoot accurate and smooth. Pretty quiet also. Havent shot it much. Stabilizer gave it 3 fps. any other suggestions that might give me a little more speed?
