    We need a little more information.

    Do you know the total weight of your arrows???

    If not how long are the arrows and what weight of tips are you using???

    What draw weight is your bow at???


    Then maybe we can get you in the ball park.:peace:

    Most of todays equipment will take almost anything you give them to shoot...that being said it will probably void any warrenty if you shoot arrows that are too lite for the set up.....what speed are you trying to reach????

    If your trying to up your speed then I would not add the 15gr, by going from 85 to 100gr heads......

    Hmm, just looked it up and IBO is 302 FPS. on that bow..

    Just to clarify, are you actually shooting a 29" arrow or is that your draw length? Because even if you're shooting a 29" arrow @ 6.2 GPI thats only 180 Grains.. Then add the 85 Gr. for the tip, and say about 30 Gr. for inserts, knock and fletching.. and that's still only 295 Gr. give or take.

    At 63#, you would be under the 5 Gr./Lb. standard given by most bow manufacturers by about 20 Gr. with a 295 Gr. arrow and I wouldn't recommend shooting that light an arrow in that bow.

    Now, if your draw length is 29" and you're shooting an arrow that is even shorter, then that would drop your arrow weight even more and that can be down right dangerous at that poundage. As far as speed goes, I used to shoot a 335 grain arrow @ 63# in my Rytera that's IBO rated at 305 FPS. and it would easily shoot 277 FPS @ 29" draw.

    Hope that helps.

    You need to get your arrows weighed before shooting them anymore. By my calcualtions you are about 15-20 grains light. :doh: These new bows are extremely powerful and can blow an arrow to peices or the limbs,cams,or strings can explode and do alot of damage to the shooter of anyone around.:Cry: Remember its all about having fun but we must always BE SAFE. :amen:

    Some very good advice here Yarddog, Take that bow to a shop and have it checked. I have seen the damage an arrow blowing up will do to someones arm. Believe me, it's not worth it.

    You could shoot the arrows that you wanted to shoot originally, but you just need to make sure that you don't break that 5 grain/lb. limit. Meaning that for every one pound of draw weight you shoot, your total arrow weight should weight at least 5 grains.

    As as example, if you were shooting a 63# shooting weight then your total arrow weight (that includes shaft, insert, tip/broadhead, fletching, nock, etc...) would have to be at least 315 grains at the minimum.

    63 X 5 grains = 315 grains total

    If you need to shoot a specific arrow length, then you would have to drop your bow's peak weight accordingly. Say if you need to shoot a 26.5" arrow with 85 grain tip. Then it would be figured like this:

    arrow shaft at 6.2 GPI would be: 26.5 X 6.2 GPI. = 164.3 grains
    tip weight: 85 grains
    misc. weight for all other parts (inserts, nock, fletching): approx. 30-40 grains

    So, total approximate arrow weight would be:

    164.3 + 85 + 40 = 289.3 grains

    So, you divide that by the 5 grains per pound and you get:

    289.3 / 5 = 57.86# or say 57 pounds max. (even though shooting about 5-10 grains under would be better) or say 55 pounds max.

    Just plug in the numbers to get an idea, but it's always a good idea to actually weight your arrows once you get them built, just to know for sure.

    Anyway, there are alot of factors that determine the ultimate arrow speed you'll achieve such as your draw length (the longer it is the easier it is to get a fast arrow), total arrow weight, and bow poundage.

    Hope that didn't confuse you.. :biggrin1:

    Hmm, I googled the Carbon Revolution shafts.. From what I can see on their website it appears that with their shafts you can shoot an underweight arrow and still be OK but I would have to research that a little bit more before I personally would feel comfortable with it.

    309 FPS. @ 28" draw out of a SB at 65# sounds phenominal! That's blazin'!

    Ok, I went to AT and looked up what people have commented on the Carbon Revolution arrows and here is one thread:

    Carbon Revolution

    I don't know, I'm kind of in the camp of 5 grain/lb. mininum.. I don't think I would shoot an arrow that light out of my bow. But, to each his own.

    I would say Grandpa's bow is screaming for some relief. Do not know all the variables but I would guess he is about 25grains light. Your bow will appreciate it if you stay above the 5gpp minimum. I like to stay about 40 grains higher than the 5gpp minimum. To me speed is'nt that big a deal. Good luck and have grandpa's arrows weighed also. :peace:
