Using back tension and getting full expansion of the back muscles will get you in line and help with the dreaded left hit which is not unusual for a right handed shooter.    Getting the body in the right position like the shot clock shown in the shooting section is key.  I had my doubts to I started doing it right and realized what I was missing.

also if you turn your face into the string and dont leave it square with target it pushes your anchor out to right from bow and will cause a shot left.....squaring up to target may help.  It could be all or anyone of these issues...

Eye dominance
Stiff spine if right handed
Bow arm swinging to left at shot
Face DEEP in anchor(turned to right..will feel lip getting hit sometimes like this)...gives longer draw but causes arrow to shoot left all things being equal. I do it and have been working to get out of that bad habit for a bit now.

proper back tension...keeping face towards target...bringing string to your face rather than trying to help by moving face as well.

Just cant the bow a little more. I like a simple fix to the problem.

I do not disagree with any of the advice you have been given. I will only add that I recently discovered what had been causing me to shoot nice groups to the left of my target. (I have been using some very light limbs to work on my form and I have been paying particular attention to my shot process.)

For me, it was the elbow of my bow arm. I was getting sloppy. When I made a deliberate effort to rotate the elbow of my bow arm until the elbow was pointed "out", parallel to the ground, the tendency to group left went away,immediately.

If my elbow was even slightly "pointed down", even a little, my group started shifting left. Too much, "pointed down", of course, caused the bowstring to whack my arm guard every once in awhile. Even a little slop in my elbow position can cause my arrows to shift left, 2"-4", at twenty yards, for this right handed archer....

Good luck.

When I hit left which also drives me nuts... It's bc I collapse. I have this little extra movement sometimes searching for my anchor when I get tired or sometimes when I am just getting going bc I'm not warmed up good and rushing the shot. For me its nothing but target panic.

I suspect its more of an eye - arrow alignment problem than a spine issue. One way to check is to draw to anchor facing a mirror. See if the string is outside to the right of your eye. If they are not in line you will tend to shoot left. overdrawing the arrow to the side of face or too high anchor point can cause this.

It has been said but try keeping your bow arm fixed on target until you see the arrow strike home...strong follow through!

I would start by adding a heavier point and see what happens.

Sounds like your bow arm. Same thing happens to me when I shoot longbows. If I'm not pushing just a bit arrows always go left. Try a 250 grain point too. May not fix the problem but it might if your technique is sound.

Lots of suggestions here, but for me, a .500 shaft cut 28 1/4" with 145gr. would be too stiff even for my 55-58# bows. Depending on center-shot of the bow, I'd add another 100gr. and see what happens.

I don't have any suggestions that have not already been made. Mike Fedora once told me that if you are a righty and you miss it will  always be left.
