draw length?

[sticks&stringz]

im confused about draw length. i have heard of two methods.i have heard of true draw length and then amo. im not sure what my draw length is.i don't understand how the wingspan divided by 2.5 is used.i have a browning medallion that's 38#@28 but i don't know where 28 inches is measured from.my true draw length from string to deepest part of the grip is 26.5 and from the throat of the grip to the front of the riser is 1.5 inches.

The AMO measurement standard is the length from the nocking point at full draw to the pivot point (deepest part) of the grip, plus 1 3/4 inches.  A 28-inch draw would be 26.25 inches to the pivot point, plus 1 3/4 inches. Your draw on that bow (.25 inches more but the riser is .25 inches shallower) is about the same so you should be drawing right about 38#, give or take a pound.

Another way to do it is to draw an arrow and have someone mark the arrow at the back of the bow at full draw and measure the length from the mark to the slot in the nock.

These measurements will usually be within a half inch of one another, which usually equates to a pound or so of draw weight.

are modern manufacturers still using amo or is that an "old standard"

I think Orion hit it on the head.  Bowyers will take actual measurements on their bows with a scale and measure system.

Maybe one of them will chime in here and explain exactly how they do it?

from what I have learned over the past few weeks, you need to put an arrow on the string, draw to your comfortable anchor and have someone else put a mark on the arrow where it stops at the far end of the shelf. mine came out to 27" most times. But it will change so don't freak out. I am the point that I really don't care what my draw length is now, I know it's 26.5 and 27. I just make sure I try to hit my anchor every time. But take what I say with a grain of salt, I have only been at this  7 weeks! but it has worked for me.

Folks measure it both ways.  Difference isn't great enough to worry about.

Agree, for most of us measuring to the outside of the bow when drawn is good for figuring arrow length.

AMO was established to make a standard for bowyers to have this standard since riser thickness varies.
