100grains:
Hey all,

In order to be ready for January archery season, I've been shooting my white oak self bow religiously.  It pulls 47# at 31", and I'm using 40-45 spine arrows with 100 grain points.  Upon release, there is significant wobble side to side, and I'm grouping arrows about a foot left of where I aim at 15 yards.  In all of my practicing I have surely developed a couple of bad habits, but I'm wondering if these have cumulated into a release bad enough to cause this problem.  With the season coming so soon I'm leery about changing anything too major in the setup, but should I mess with the point weight? Other than aiming right, what do you guys think I should do in this situation? All help is greatly appreciated.

Urufu_Shinjiro:
I think they may be too weak in spine, how long are they? I'm assuming they are at least 31", the longer they are past 28" the higher the spine you need.

DC:
I would try a substantially stiffer arrow. Depending on your tip weight you could reduce that some to try.

aaron:
it's really hard to diagnose these things from afar. As far as spine goes, we'd have to have more info to make a good guess (are you right handed? how wide is the handle of the bow?) My suspicion is always that spine is too stiff.
For form, we can't even guess without some good video.
Other questions I have are about your groups- you say they are a foot left... but how big are the groups?
How long have you been shooting?
Have you bareshafted your arrows?
Everyone has to decide for themselves if they are ready to hunt.
My advise is to try more point weight to see if that helps.
On a deer sized animal, an arrow that misses to the left or right by a foot is a disaster.

Pappy:
A 40/45 splined arrow at 31 inches is more like 25/30. The lighter 100 grain points would help off set that but not enough, my guess is to light. Get really close to the target and shoot, say 15 feet and see how the arrows hits ,tail left in the target it is to weak, tail right to stiff for a right handed shooter. ;)
Are you drawing a true 31 inches or you think you are ?? that is a very long draw. ;)
