So, I sold my compound arrow projecting machine and all associated jewelry (insert laughter) and purchased my first longbow, arrows, etc. (insert applause).  Here's my current dilemma.  I've been practicing religiously since I switched over and my groups are consistently getting tighter as my form and instint improve.  However, I also seem to shoot fairly consistently LEFT of the bullseye.  I read that  using a thinner pad in my sight window could potentially solve this issue.  So...

A) is that correct?

B) if so, what suggestions do you have for what I can use to replace the already fairly thin leather side plate of my Bear Hair Rest?

Let your answers and your arrows fly!

Thanks,

1. you might be canting your dominant eye over the arrow.
2. you might be twisting the bow or applying to much pressure to the bow handle
3. Or you might be using the wrong arrow.

Best medicine is to video yourself shoot from all angles and then play with different arrows.

this is just my opinion from the many things I have tried and found what has worked for me that you may not be canting your bow enough.  try "opening up"  the sight window by canting the top limb to the right more and see what happens.  It worked for me,  let me know.  I just started hardcore trad after 30+ years as a compound shooter just last year and it has been a long journey of trial and error but well worth it.  Good Luck!

You'd probably get a better answer if we knew if you were right handed or left handed.
That's IF you're arrows are the problem.
If you started shooting about 10 yds from your target, like most shooters, that also could be an issue.
Start close, say 5-10feet will tell you allot about your form and what you may have to work on.

Arrows may be a little stiff for the brace height you're using have you lowered the brace height a few twists? Many times it may be too much heal in your grip causing torque. Move that hand around the grip using more palm pressure. Or it could just be the need to concentrate on that bow arm staying solid. I have to constantly remind myself of that one.

One other possibility is you might be collapsing on release- that is, if you're right handed.

I'm right handed.  Thank for all the advice.  I'll definitely consider each of your suggestions.  And please feel free to keep them coming!
