archery question: arrows and broadheads that are too light?

[SkaerE]

i have a browning compound bow set to about 60lbs or so. anyhow, im using 31'' carbon fiber arrows ("carbon-wolverine" - that say they are for a draw weight of 60-70lbs) but dont say how much they actually weigh. also using muzzy 100 grain broadheads.

the arrows weigh considerably more than the broadheads by my "calibrated left hand to right hand comparing scale"

now, in the browning manual it says i shouldnt use arrow/broadheads that weigh in less than about 360 grains or so. i dont have a scale, but i know that 437.5 grains is one ounce...

shoots well, just wondering if im gonna hurt the bow.

thanks

Weigh them! Or at least find specs on the web about the shaft. You must know this. You should shoot at least 6 grains of arrow wight for each pound of draw. I prefer more like 8. Also check your balance (FOC) as it makes a difference too, especially if you don't have enough. More is better unless you are a target shooter 40+ yards.

There is no substitute for a good bow shop.

Print that PDF off and read it once a week until you know it by heart. Seriously, it will be more valuable than you could imagine. It will teach you what you need to know about making arrows fly PERFECTLY!!!

Arrows that are too light, under 360 grains is a common cutoff point, are very much like dry firing the bow. Limb velocities are too high, and vibrations much stronger. Limb delamination can be EXPLOSIVE and people can get hurt. Strings will break more often and limbs will blow up more often with ultralite arrows than they will with heavier arrows, that is just a fact of life.

Weigh your arrows, or find the weight of the shaft per inch, the weight of the inserts and fletching and add it all up. I would shoot down to 300 grains for target shooting IF I had Limbsavers on the bow. For hunting 360 is ROCK BOTTOM on weight and too light for all but perfect shot placement. Perfect shot placement does not happen often so bulk up to 425 grains minimum IMO.

If you don't have a pair of "Limbsavers" on the bow GET SOME!!! Only those that have never tried them don't use them. I will NEVER shoot my bow without them again.

Yeah limbsavers pretty much rule.
