Correct Arrow Weight
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. |
RE: Correct Arrow Weight
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.

RE: Correct Arrow Weight
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.

RE: Correct Arrow Weight
That's including broadhead/field point weight, correct?
|
RE: Correct Arrow Weight
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.

RE: Correct Arrow Weight
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! ;)). |
RE: Correct Arrow Weight
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.

RE: Correct Arrow Weight
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? |
RE: Correct Arrow Weight
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
|
RE: Correct Arrow Weight
Im relatively new to bowhunting, and ive been told this before, but what do the numbers - for example- 2315 represent?
|
RE: Correct Arrow Weight
The number 2315 is actually two two digit numbers. The first number indicates the outside diameter of the arrow shaft in sixty-fourths of an inch, and the second number indicates the wall thickness of the shaft in thousandths of an inch. A 2315 shaft would be 23/64" in diameter and have wall thickness of 0.015".

RE: Correct Arrow Weight
Remember a heavier arrow is a more accurate arrow. The most accurate arrow will be the one that groups best out of your bow. That will depend on your draw poundage, power stroke, cam style, nock travel, foc, arrow length, arrow spine, etc.... It is way too much of a generalized statement to just say that the heavier arrow is inherently more accurate. |
RE: Correct Arrow Weight
I have to agree with DarrellH, tex. That 2315 is way overspine for 55 pounds and 28" draw with a 100 gn tip. You need to be looking at the 2215 instead. 2117 is also correct for you, but it's substantially heavier than your 2315. I'd be inclined to go to a 3-39 ACC, if you can afford it.
Or, for a more affordable arrow, try the GoldTip XT in 5575. It'd be fine for deer, though I'd probably go with the heft of the 2117 for anything tougher... like hogs, for instance. |
RE: Correct Arrow Weight
Oh-oh,
I may have a problem. Since reading this I did a bit of measuring and am coming up short on my arrow weight. Can comeone tell me if I am shooting the wrong arrows? PSE Carrera 70# draw weight 30in draw length 29in arrow 100 grain broadhead 3 blazer vanes I come up with 349 grains - am I wrong? According to Carbon Express the CX300 I am using is ok. They list it at 8.1 grains/inch. Blazer vanes are approximately 5grains/vane(?). |
RE: Correct Arrow Weight
Ok. My carbon express arrows are a whopping 11.4/gr per inch. At 26.5 inches + 100gr field tip that comes to 402.1. Vanes count towards weight? If so, how much do they weigh? I'm guessing 3 to 5 gr each?
That would put me in the 420 to 428 range. Is that too heavy or a good middle ground? ORIGINAL: zak123 Yes, it includes everything on the arrow. |
