So I purchased a Hoyt Spyder Turbo in the 70-80 pound limbs and a 29.5 inch draw. I don't have full intentions to max the limbs out. Thinking about setting it around 75-76 lbs. Would Easton FMJ .300 with a 125 grain broad head be alright for this set up or is it under spined. My Heli-m is around 72lbs and I shoot the .300s.
Unfortunatley,at that poundage with that bow,a .300 shaft will be too weak. Assuming the raw shaft length is in the 28 1/2"- 29" length. You may be able to get adequate flight with them and mechanicals but I doubt you will be able to get fixed blade broadheads to tune. A .250 spine is perfect so if you want to keep that poundage and shoot fixed blade heads,you may need to get some Easton FMJ dangerous game .250 shafts. Another option is going with an overdraw and shooting a 27" or shorter shaft. OR,lower poundage to 70#
hahahaha. I would say for that length those arrows are probably a little underspined for that draw weight.
Haha no godzilla here. I'm really comfortable with 70 so I figured I might bump it up a little and see how it is. My helim is 72 lbs and I shoot the 300 FMJ and I get a lot of arch in my shot.
How much speed will I sacrificing with a FMJ 250 at 17.2 grains per inch? I'm not to crazy about speed but I want to keep it around 300fps I'm not sure if that is possible.
You could shoot a 100#and you will get a lot of arch in your shot. It is called arch..ery. sent from my samsung note 2
To keep around or above 300 fps, you need to go to an overdraw and cut your 300's down to 27" or less. If you go with the .250's. You will need to shoot the 75 gr brass inserts with the 125 gr heads just to have the foc in the 11% range. The arrow speed will most likely be in the mid 250's with that arrow. You could lower your poundage to 70 with the current 300's and most likely be in the mid 280's and spine will be close. Im assuming a 28 1/2" raw shaft length. sent from my samsung note 2
Ok, so I called and changed my order to the 60-70# model. I guess I should of did my research before jumping up to the 70-80. I just don't want to sacrifice that much speed from a bow that is built to be pretty fast. I should be alright to shoot a .300 fmj with a 125 grain muzzy with the 29.5 draw, right?
Don't give up yet. I did a little more research and gold tip makes a kinetic xt in a 200 spine that is 11.6 gr per inch. This would put you right in the 300 fps ball park. sent from my samsung note 2
Tuned a few Spyders this year, one was a Spyder 34 Turbo but we maxed it at 62..... Just my two cents.....first off, if you back your 80lb down to the low 70's be careful with the draw length, you most likely will see an increase. Here is what I would do: Back the bow down to 72-74 ish and make sure your draw length is still correct. The Spyders have plenty of room on the shelf ...I would use a rest( QAD, Rip Cord, ect) that would allow you to cut your arrow back to the 26.5 or 27 inch. I would use a .300 spine arrow and try the 125 grains up front but I most likely think you will have to switch to 100 grains....By the sounds of it you already have .300's so you might as well try to make them work....
The 300 fmj should be doable at 70. It is showing just slightly weak but I doubt you will get 300 fps. What are you getting now? Personally I think your putting way too much into the 300 fps number. It's just a number. sent from my samsung note 2
Trial is correct. The 80# limbs backed off to 70# will increase the draw length a little. Maybe as much as a 1/4" to 3/8" sent from my samsung note 2
Trial, do you think he could get his arrow that short with a qad, even with the hoyt brace? The best I'm seeing is 27 1/2" raw shaft. (28" arrow) sent from my samsung note 2
I have friends that shoot over draws that go behind the brace. The machine shop I work at even built a couple for chase fulcher (hoyt pro staff hunter) he had a couple extra built for randy ulmer and a few others. I know they are the new craze again but Im not buying into them. Just offering up another option. sent from my samsung note 2
Yeah, all the info sound great, I just feel like if I get the 60-70 model that I wont have to be so limited in certain aspects. I've just seen a lot of reviews on this bow and it seems most people are getting between 290-298 fps with different set ups. Like I said ive never been to crazy about the whole speed thing so I don't think it will be to big of deal.
From the Spyders I worked with I think he might, at the very least he an take a 1 1/2 off and get down to 27" which should be fine ....there was enough room to tweak the rest off the shelf without hitting the brace.
I agree that 70 opens up your options. Easier to sell down the road too. Not to mention a little less stress on the shoulders. sent from my samsung note 2
