Default RE: How to set up my Arrow's Specs

I'm thinking those are going to be underspined for your set up. Give us more info on your bow. I have never heard of it before. Is it an older bow or what?

True AMO draw length, not the length of your arrows or what "Some guy told you" or what the bow says it's set at. If you don't know how to check it, here is how. Put an arrow in it and draw it back, have someone mark the arrow right above the inner most part of the grip. Measure from the valley of the nock ( I just leave it nocked on the string and measure from the string) to the end of the shaft, not the tip of the finnished arrow. Then add 1 3/4 inces to that. That is your draw length.

We would also need to know what length arrow you are going to shoot. It should technically be about an inch shorter than your draw length. However if you shoot an older bow it may be a bit longer becsause of clearance issues with the riser. Or it may be shorter if you shoot an overdraw.

How much draw weight are you pulling, you should really have it measured if you haven't done it in a while. Draw length, arrow length and draw weight are the most important factors in getting the correct arrow. Not exactly things you want to guess at.

What kind of cams are on it, dual hatchet cams, single cam, eccentrics? Or do you know what the IBO or AMO rating was for it new. This helps determin how effetient the bow is. Some bows devolope much more energy than other ones, even when set at the same specs. Also what is the axle to axle on the bow.

I tried to look up some information on this bow the other day to respond, but I couldn't really find much. Most of the hits I get are for a gun safe with the model name Bridger. A few of them were for bows, but no real information to speak of.

If this is an older bow, I would suggest not shooting the carbon force 100 arrows out of it, Even if the spine is close to being right. They are very light arrows and will not be good on your bow. The older bows were just not made to take that kind of abuse. It's not even really that great on the newer ones unless you are shooting a weak set up.

I am thinking of picking these arrows for my bow. I only shoot 26 inches and 60 lbs of draw weight though. And I will only be shooting 24 inch arrows. I can't see these spining correctly on your bow at 30 some inches if your draw length is any where near that.

Going from 400's to 100's is a pretty big drop in weight and spine.
