Minimum Arrow Weight

[grassmaster]

I have a 70# draw with a 29" draw lenght and the sticker on my bow has a minimum arrow weight of 420 grains. What gives? Can I safely shoot a ligher arrow as long as the spine is stiff enough?

use a grain scale to get the wight of your arrow with the head on. Divide that by your poundage and make sure it is above 5.0. If it is below 5.0 then you need to do something to make the arrow a little heavier. At least that is what I have been told by several different folks that should know what they are talking about. A lot of arrows show the grains per inch on the arrow. If you don't have a scale just measure your arrow and multiply the legth by the grains per inch + 15 grains for vanes + 10 grains for insert + 5 grains for knock + amount of grains of your broadheads = total arrow grains. Divide that by your bow poundage. That is what I do anyways

you "can" shoot whatever your heart desires. is it advisable "no" and in most cases void your warranty.

What Codie says is correct for bows that are rated at 5 grains per pound, but if yours has a sticker that says a minimum of 420 grains, you may void your warranty if you go lighter than that. What kind of bow is it?

[bowhuntntxn]

420 gr arrow equates to 6 grains per inch. Most manufacturers will not warranty limbs if the arrow is below 5 grains per inch. I think the average hunting arrow is somewhere around 9gpi, and they go down from there into the lighter target configurations, and the lightest that I have seen made by Easton was 6.5 GPI. High Country makes a speed arrow that is somewhere near 3 GPI, and they are the ONLY mfgr. that recommends shooting them. The lightest you could shoot and still keep from voiding your warranty would be 350 gr. at 70#.

no, ever see an arrow explode?

the hca speed pro come in to sizes a 5.5 and a 6 i due beleive..

I've always used the 5 grain per pound rule too, although I shoot a 400 grain arrow in a 65# bow. You'll loose a little speed with a heavier arrow, but it'll also shoot quieter.

What kind of bow is it that reccomends a 420 gr arrow?

I am shooting my Speed Pro at 5.2 grains per lb.

Been talking to HCA about the performance and they are totally acceptable to that weight.
The rule as everyone says is 5.0 and above. I would call the dealer or manufactor and ask "why?"

[grassmaster]

I would love to call Archery Research but they are no longer in business... I love my bow (AR34) and it shoots great. Currently shooting a 390 grain arrow with no problems. With the 5 grains/pound rule, it sounds like I should be ok

hey where did you get your arrows..

[hcshooter]

HCA sent me some dealers to order them from, send me your email and i can forward that to you.

I shoot a 400 gr arrow out of my 62 lb Conquest 3. I believe in the 6 grs. per lb which I feel is a good compromise.

[Mike Javi Cooper]

depends on when the bow was made... you folks is giving advice based on newer bows... I got an older Bear with stainless cables and wooden limbs/ riser and I'll dare y'all to shoot it twice with a 5gpi arrow...
