Title: Help settle an argument
Post by: DoubleJ on August 30, 2010, 01:28:32 PM: A co-worker and I were arguing about arrow vs. draw length. I won't say who was on what side since I'm not 100% sure of my position. One of us said that, with a 28" draw, using anything longer than a 29" arrow would be a bad idea. The other one said that, with a 28" draw, using a 31" arrow was perfectly fine. Who's right?

For the novice - why do you shoot 32" for turkeys? stabilize faster or something I am missing?

Post by: carpsniperg2 on August 30, 2010, 01:53:02 PM: because my bull heads i have been shooting will not come back onto the shelf. my arrows have to stick past the riser of my bow when i draw back to be able to shoot those heads because they are so big.

Post by: Todd_ID on August 30, 2010, 03:16:24 PM: Either one could be right. It depends on the equipment. The only bad idea is to use an arrow that's too short and cuts your finger when you shoot.

Post by: garyltbh on August 30, 2010, 04:05:34 PM: I like to shoot arrows that are 1 in past my rest. I shoot a 27 in draw and my arrows are 26.5 in. I use a ripcord drop away rest. I beleave its just personal preferance as long as you are spined correctly.Like what was already said.

Post by: yajsab on August 30, 2010, 09:55:24 PM: Just for the argument sake, longer is fine. Short behind the riser is not preferred. :twocents:

Post by: bullcanyon on August 31, 2010, 05:05:06 AM: Shorter is actually better if you can get away with it. Problem is with most drop-aways is that they don't raise till the last 1" of draw and that is not before your broadhead drags on your riser. If you use a rest like the ripcord or quad you can use the short arrow because they can be cocked before you draw.

Think of the shorter arrow like shooting pool and having your hand closer to the cue ball. Less margine of error. Put your arrow in between your middle finger and pointer finger. Hold the nock with other hand and put next to your cheek. Now have it sit just barely past fingers and wiggle the nock back and forth. To it again with it farther past fingers. Will be more movement. Same principle.

Post by: Matt on August 31, 2010, 07:42:02 AM: Length is irrelevent for the most part. Spine is the most important then forward of center (FOC). For hunting and fixed blade BH's you want to make sure that you are in front of the shelf with the BH and stiffer is better to a point. A weak arrow will not group with BH. For FOC you want about 13%. Put all that together with how long you want your arrows to be.

Post by: DoubleJ on August 31, 2010, 08:45:31 AM: The arrows in question are being shot from a 28" draw. They are 31", without broadhead weigh 390gn, have a spine of .343, 100gn broadheads and and FOC of 10.2%. Total arrow weight is 490gn.

.343 spine with 100 grn BH I would not go beyond 30" for arrow length - regardless of draw length.

Post by: DoubleJ on August 31, 2010, 11:35:50 AM: 125gn broadhead balance it out a bit better? Then it's over 500gn and would slow way down

Post by: Lowedog on August 31, 2010, 02:05:48 PM: I would say that with a 31" arrow you may be a bit under spined. Going to a 125gr head would make it more so.
