wtnhunt Posted March 4, 2008 Report Share Posted March 4, 2008 Finally got the draw length right on my new pse bow, and it feels much better to shoot, which is great. Shot a couple dozen arrows over the weekend and it seems like this bow with my small diameter carbons is not shooting as fast as my old setup did with the same arrows. This new bow is supposed to shoot around 306 fps from what the tech told me. The old bow was a fireflight 33 and it was rated around 10-15 fps or so slower if I remember right, but it shot flatter than what I am seeing out of this new bow. If the new bow is rated to shoot faster, it should shoot flatter, right? Only thing I can see possible is that it might be rated with a lighter arrow. Any other logical explanations?

Dubie Posted March 4, 2008 Report Share Posted March 4, 2008 I'm sure they used some kind of feather weight arrow trick to jack up thier speed number. Most people I see looking at bows these days go straight to the tag and check out the speed rating before deciding weather to even pick it up or not.

LifeNRA Posted March 4, 2008 Report Share Posted March 4, 2008 Fire it through a chrono William and see what it does! I really don't believe in the speed rates they give a bow. Quote Link to comment Share on other sites More sharing options...
wtnhunt Posted March 4, 2008 Author Report Share Posted March 4, 2008 Wish I had a chrono, but dont have one John. Really think it is likely that this newer bow would allow me to shoot lighter arrows and that is where they came up with the faster rating, that is about all I can figure. My old bow, I had to shoot kind of heavy arrows, minimum total weight was 420 grains if I remember right, and I was just a bit over that with 100 grain heads. Guess I might try and ask someone at pse what the lowest grain weight I can get away with shooting with this bow. Quote Link to comment Share on other sites More sharing options...
Dubie Posted March 5, 2008 Report Share Posted March 5, 2008 I think the standard is 5 grains per pound for thier tests. Quote Link to comment Share on other sites More sharing options...
Straight Shooter Posted March 5, 2008 Report Share Posted March 5, 2008 Yep, 5 grain per pound on most warranties from bow manufacturers. Question for you, though. Have you shot from all distances yet? If so, how is the pin gap? Did it tighten (closer together) up from the last bow or did you have to open them up some? If you tightened them up then your bow is shooting faster, if you moved them apart, then your bow is shooting slower. If you went to a bigger diameter arrow it will change your pin gap as well. IBO rating-if your bow is set at 70 # draw, don't go below 350 grains on your arrow weight. Quote Link to comment Share on other sites More sharing options...

IBO rating-if your bow is set at 70 # draw, don't go below 350 grains on your arrow weight. That is how I judged that is not shooting flatter and likely not as fast. The pins have opened up from where they were with the old bow, it is the same sight that came off the old bow. Arrows are still the same small diameter carbons I had been shooting with the old bow. The min arrow weight for the old bow like I said was 420, think with the heads and nocks and all my arrows were in the mid 440's total weight when I figured them up. Would an arrow 80-100 grains lighter fly that much faster? If so, I guess that is where the difference comes in. Quote Link to comment Share on other sites More sharing options...
Straight Shooter Posted March 5, 2008 Report Share Posted March 5, 2008 On a standard you will lose/gain about 2-3 fps for every 10 grains you add/take away from your arrow. Quote Link to comment Share on other sites More sharing options...

Thanks for the replies, that makes sense and is kinda what I figured. So basically my new bow that is supposed to be faster is actually rated a little faster based on a lighter arrow, but really is shooting slower because I am shooting a heavier arrow that was around the min weight suggested for the old bow. Guess I could look at getting some new lighter carbons or just stick with shooting an extra pin for now. Quote Link to comment Share on other sites More sharing options...
Straight Shooter Posted March 5, 2008 Report Share Posted March 5, 2008 That is always a bit of a disappointment for buyers when they get their new bow home and it isn't shooting as fast as advertised. You've just got remember that they are listed at IBO speeds of 5 grains for pounds and our hunting set-ups are much heavier on weight. HCA has their new bow rated and warranted down to 3 grains per pound, that is just about dry firing. Quote Link to comment Share on other sites More sharing options...
wtnhunt Posted March 5, 2008 Author Report Share Posted March 5, 2008 That is always a bit of a disappointment for buyers when they get their new bow home and it isn't shooting as fast as advertised. This was not a new bow purchase, but was a bow that was a replacement from pse on a bow that I had bought new 6 or 7 years ago that had a limb crack on me back in November. The bow was supposed to be comparable to my old bow in performance, and it may be closer with lighter arrows. Quote Link to comment Share on other sites More sharing options...
Straight Shooter Posted March 5, 2008 Report Share Posted March 5, 2008 My bad, I was under the impression this was a new bought bow. Quote Link to comment Share on other sites More sharing options...

No bad there at all, if anything probably more so my bad for not saying in the original posting:o. I had posted about the deal with getting my replacement bow a few times in here a while back, you probably missed those;). Thanks again though, you helped reinforce what I kind of figured:rolleyes:.

HUNTINGMAN Posted March 5, 2008 Report Share Posted March 5, 2008 I wouldnt worry about the speed so much,as long as it is quiet,feels good in your hands and you can shoot it acurately.People have been killing animals for many years out of bows that dont leave a vapor trail behind the arrow.

Guest bigalt78 Posted March 7, 2008 Report Share Posted March 7, 2008 well really speed isnt the most important thing although im a speed freak myself. but the tech who told you that didnt explain it better to you. that 306 fps is ibo you have to have the right draw length right arrow weight right poundage everything has to be ibo and perfect to get that speed. I shoot a pse firestorm x and im getting around that speed with a radial x wieve 400 but i have a 30 inch draw and im shooting 84 pounds. but with you i dont know your draw length and pounds. I notice you said it might be the arrows but your arrows change size depending on the pounds you shoot like a heavier draw weight needs a heavier bigger arrow. I think if you got your draw length right and your bow is maxed out on pounds your shooting as fast as you should be as long as your shooting the right arrows probably because of your draw length but if i could recommend something to you i would say not to go out and buy lighter arrows to get more speed when it comes to hunting that's going to hurt you i would just go with a heavier arrow because the main thing in hunting is kinetic energy you dont want a light arrow that goes real fast versus a heavier arrow that might go a little bit slower because that heavier arrow is going to blow through a lot more animals.

Really am not all that worried about the speed, but I did like the flatter shooting, I was able to get away pretty well with one pin with the old bow under hunting situations. New bow, will be forced to shoot two pins. Little more checking showed the old bow was actually rated at 303 fps ibo, so it probably was faster with the heavy arrows I am using. Guess the tech was a bit misinformed about my old bow. Quote Link to comment Share on other sites More sharing options...
