When shooting my one bow, if I don't overly cant my bow I will send the arrow WAY left. It kind of seems like it came out of the blue but I'm not sure. The bow is fairly new to me, and I started out shooting it awesome, and still do, except that my groups have shifted left. Extra cant solves the issue, but is there some other root cause I can correct instead? Or do some bows just "point" different?

Weight at your draw and what shafts/length/point weight are you using?

Is your 'one bow' a longbow (without a center cut shelf) by any chance?   If so, what's your other bow or what are you more used to shooting?

Try adding a lot of point wt. to a couple of arrows. See if they change point of impact. Let us know what happens.

Did you change the way you grip the bow??

sounds like the arrow is too stiff but hard to say without more info. The nock point hasn't moved on you has it?

I am having the same problem, causes I have identified for me.
1. droping my bow arm after release
2. overdrawing past anchor
3. plucking the string.

I had this happen to me once. I found that i wasnt lifting my head enough when the bow was held straight up( i was holding it like i do when it's canted)So i just adjusted my head location and it fixed right up. basic i know, but maybe it hasnt been tried yet. Good luck and i would love to hear how you solve it.

Make sure you are anchoring tight on your face, sounds silly but it is a quick fix if you start letting your hand drift away from your anchor point. It happens to me when I start the plucking thing.

if the grip is much different it can be a big change.

I put one of those selway rubber grips under my wrap. It felt good but extended by grip enough that somehow it was causing hand torque. I took it off and was shooting fine again.

I shoot a longbow. Noticed if I lean my head more arrows go left. Might be the problem

This post is what I realized was my problem with hitting left, and it has changed my accuracy by a huge amount. It only happens now when I get tired.

When I shoot left, I am pulling my release hand down and away from my anchor point as I release. This causes my arrow to hit hit left.

One is a Martin recurve shooting off a flipper. The other is a longbow cut past center shooting off the shelf.
When I first got the martin I could almost interchangeably shoot them with no issues.  

As I've spent a little more time with the recurve, when I first start out, I am way left, and have to make an effort to correct it.

I thought maybe my original quick bareshaft tune was off some. So just to go extreme I went form 200 gr up front to 300 and I still get left. Arrows are flying like darts, no issues there. Just way left if I relax and don't mentally keep after it.
I'm guessing its just a matter of grips between the 2 bows, but I thought it odd to start out with no differences but develop a left tendency on the one.

The bow is 55# @ 28, which is about what I draw. Shooting 28.75" Heritage 250's with 212 gr up front.

I shoot left handed and my arrows were drifting right. I thought at first it was spine, but realized it was my release. My hand was comming off my face.

Ok guys I started cutting into the sideplate little but little. I finally believe I have things straightened out. Man my groups were tight, but all left. But I've gotten them to move over. Once I shoot again tomorrow if I am hitting dead on I will be happy.

As I understand it, grouping left and the need for closer to centershot indicates a stiff arrow. I've only tuned a few bows for myself, so other peoples experiences are valued as info. Please keep us posted and good luck with it.
