Correct Arrow Weight

Primitive Weapon · 09-17-2005, 02:12 PM

What is the "formula" used to determine correct arrow weight? I'd like to shoot the lightest arrow I can......safely.

My Diamond Victory bow is set at a 28" draw and 60lbs.

I believe the rule is 5 grains per pound of draw weight, which would mean you could shoot a 300 grain arrow. That is very dangerous though. I believe the safe zone is shooting an arrow is 6 grains per pound of draw weight, which means you could shoot an arrow that is 360 grains.

This is sort of a tough question to answer as Zach has just shown. Many companies will insure their bows down to 5 grains per pound of draw weight though I don't really see the need for an arrow that light in bowhunting situations. Generally, I think an arrow that puts out good KE and momentum numbers to be the best route to follow. In my experiencecombining that along with a relatively flat trajectorytypicallyresults inarrows in the 6 to 7 grains per pound of draw weight range. In your situation that would be between 360 and 420 grains. I would be tempted to aim closer to the 360 mark since your draw length and draw weight combined are a little bit lower than average.

That's including broadhead/field point weight, correct?

Yes, it includes everything on the arrow.

Go to Steve Jackson's site, http://www.bowjackson.com ,and look under arrow shaft charts. There you will find the AMO Minimum Arrow Weight chart. Click on that and you'll find the answer to your question.

I like that bowjackson website. It is amazing.... With my classic setup, I'm right on the money:

65# bow, 30" draw, 41" ATA round wheel dual cam lefty bow. The most popular setup is an Easton aluminum 2315 armed with a 125 grain field tip/broadhead. Total arrow weight: 568 grains (flying tire iron! ).

Also depends on the distance you will be shooting. www.eastonarchery.com is also a good site, it will give you a chart to select arrow weight. You don't want to go too light, because then you will lack kinetic energy and penetration. I shoot 55# @ 27" and use a 2117 tipped with 100 grain heads...a lot of people told me this set-up was way too heavy and stiff for my set-up, butI cangroup the arrows within 1-2" @ 20 yards, and at 30 yds they are about 1/2" lower using my 20 yd. sight pin. I think the heavier arrows may cause issues (such as loss of speed)if you are shooting much over 30-40 yds. but that's a heck of a shot with a bow anyways. If you are staying under 30 yards I would recommend going with a littleheavier arrow.

Not to make a new thread- im just gonna post a question here.
Im using a 55lb compound bow with a 28 inch draw length.
Currently using 2315 XX75 arrows. For hunting I slap on a muzzy 100 grain.
Is this a good arrow for my setup?

Remember a heavier arrow is a more accurate arrow . It also has more energy which will get you more penetration. So you may be ok shooting a light arrow but should you
