Expected speed?

[parshal]

What should I expect for speed from the following?

60" Predator 54# @ 28", scaled 50# @ 27", my draw ~27.5"
30.25" Heritage 250, 145 gr tips, 510 gr overall weight

My chrony shows an average speed of 163 fps.  I have a 42# 60" Predator that averages 184 fps with 355 grain GT 15/35's.  I figured the 54# would be faster than it is but I thought I'd check with you guys first.

My 60" limbs, 52#@32" chronied at 198fps with a 425 gr. arrow.

There is a lot of difference in the weight of your arrows.

No doubt there's a big difference.  I was just curious what others are getting and if what I'm seeing is expected or not.

That's a great bow and it sounds like a reasonable speed to me for that GPP. If you want to go fast you need to drop arrow weight, but that sounds like a great hunting setup. How are your groups?

A few things that will make a bow looks slow on a chrono:
1- string to thick/nocks too tight
2- bad release, drag finger off string
3- silencers
4- is the draw length 100% for sure?
5- is the scale 100% accurate?

You add up some combination of those 5 things and you might be able to get 8-10 fps without touching the arrow setup. That's no promise, I've just seen each of those through numbers way off.

Predators are GREAT bows, congrats!

The scale was at Rocky Mountain Specialties (a sponsor here) so I assume its quite accurate.  The chrony is mine from my reloading days and was shot with a bare string (no nock point either).  I'm sure my release isn't perfect however the speed was quite consistent.  Groups are good when I do my part.  I'm still working on form.  I have been using the 42# more for form work.

Maybe I been shooting longbows too long, but that arrow sure sounds stiff for a #51 bow thats just cut to center. But if it fly's....

Go back to RMSG and shoot through their chronograph and compare the two speeds. Your shooting 10gpp and you don't have an exceptionally long draw, that's probably a realistic speed. I shoot 10gpp at 31" draw and get about 182fps. 163 is nothing to sneeze at.

[Charlie Lamb]

While Chrony's are useful tools, they can also put some bad psych on your head. With good sharp broadheads and accurate shooting that bow will push a multiblade head clear through an elk.

My personal experience on both comments.

If speed is so important, probably a bow with wheels should be looked for. Dave

[JamesKerr]

That sounds about right.

[JParanee]

I am shooting 2 bows right now the first is a Titan riser with a set of Dryad epic limbs at my 27 inch draw is scaling  50# and shooting a 530 grain arrow at 176 fps

The second bow a Morrison  riser with BF Extreme limbs is scaling 54 # at my 27 inch draw and shooting a 520 grain arrow at 194 fps

[parshal]

I'm not real concerned about the speed but, since I had the chrony sitting there, I thought I'd check it out.  I'm just not sure what to expect so I thought I'd ask.

I don't see how you could assume parshal would want to abandon his traditional bow for a compound based on him asking us if we thought the numbers he was getting out of his bow was consistent with what we are seeing as far as traditional bow speeds goes.

[KHALVERSON]

im assuming a hunters niche predator
i would expect around the 170 mark for that bow
predators are one of the quickest bows ive shot
+ mike and ron are great to deal with

[Shakes.602]

Just a Tad faster than you can run, or hand chuck the arrow!!      

[snellville-dave]

Don't take my remark as being serious Maui man, just a little stupid comment. Dave

[kawika b]

Gotcha Dave... sarcasm and things said in jest are hard to interpret sometimes.

[Wudstix]

Maybe you're not holding your mouth right.  As Cahrlie said don't let speed get in your head, have not had a critter yet complain about how fast the arrow pasted through them.
