Since I started shooting on a daily basis since September, I noticed that my arrows hit the target canted from left to right. I shoot a lefthanded selfbow. Today I decided I should weigh my arrows. All of my arrows are in the 420 to 450 grain range. My question(s) are:
1) What should an archer expect to happen when he/she shoots arrows that are less than the 10 grain per pulling pound standard?
2) Is it safe to assume that if I had used 600 grain arrows with the #47 bow, I would have seen a right to left cant?
3) Could this be a spine issue instead of a weight issue?
4) What is the general rule for what spine to use on a specific poundage selfbow?
I know I have a lot of questions, but lack of archery knowledge causes limitations in the field.
Thank you for your help!!

Read OL's section on tuning, http://bowmaker.net/index2.htm, bareshaft tunning is the way to go IMO.
Sounds like a spine issue if you are shooting your bow vertically, if your are canting then nock position could also be off. In my experience arrow weight alone does not effect spine, just stiffness of the shaft its length amount of fletch and point weight.
I would think since selfbows are not close to center shot a softer spine would be needed.
The link doesn't work. Just thought I would let ya know.
Try this one

Arrow mass weight shouldn't affect arrow flight like this. This sounds to me like a spine issue. Shooting left handed, nock right indicates a soft spine. Try lightening point weight or shoot one without a point and see if this makes a difference. You could also shorten the shafts, but this isn't reversible like changing points.
Thank you for your input. I will read the information on the link in the morning and see what I can do to resolve this issue.
