This happens to me If my grip changes. I shoot a longbow, and if I absentmindedly use a more straight wrist grip, the arrow goes wild. If I remember to put the pressure on the heel of my hand, all is well.

I think you said you are shooting a recurve, so you need that pressure on the web between thumb and index finger. Or at least, the same grip every shot.

See if perhaps in regripping the bow you might be changing something.

Hrm, have you done a spin check on those broadheads?

I got out and shot today, and I think I've got the problem solved. I do however believe that my arrows are border line to weak, which is going to magnify any errors. I don't want to sacrafice any weight, and I've got no room to trim on my arrows with my draw length.

I started by aligning all my broadheads as perfect as I could horizontally. I had been shooting them vertically. I aligned them by picking from the arrows I had and trying them until I found a head that matched up with an arrow the way I wanted. Today I used rubber washers so that I could tune them exactly where I wanted them.

I think the real problem was in my form. I shot with I friend today and paid extra close attention to my achor point and release. Turns out I've had a tendancy to pull back a little just before I release. When I'm solid on my anchor and just "quit holding to string," unstead of thinking about releasing, my arrows flew great.

Next year I hope to go up in bow weight and get away from this spine problem, and hopefully solve my problem of wanting to overdraw my bow as well. A change is just not an option right now.

Thanks for all the advice.

bare shaft at 10 yards with field points.  then report back.  

If borderline weak, then build out your arrow plate a little. That will fix that problem.

I'd say Charlie is onto something.

1) I learned from a bowyer/tuning source that if a bow is cut to center or beyond, as he put it, it will "require a stiffer shaft to tune, but those arrows, coming off a finger released string, aren't sure which way to paradox, shot-to-shot," so shimming out the side plate a bit helps improve flight & tuning.

2) If you're on the edge of weak, shimming out the sideplate will make the arrow 'act' stiffer and may improve your flight considerably with negligible impact on where you're hitting!

Otherwise, you're going to need to have that "excellent" form, release and follow-thru EVERY shot or as you said, that 3rd/4th one will show you're not in the middle of the bell curve of proper tune!

Under field conditions, that "perfect form" seldom happens and wounding can result!

3) shot to shot inconsistencies are best fixed "shooting the bale" at 5 yrds or less, over and over, focusing only on your form throughout the shot. I personally find it boring as sin, but, it sure seems to get me in the "groove" better, faster.

300-400 shots! Wow! I wouldn't be able to move for a week!  

If you want to "experiment" with side plate shimming, just get some plastic electrician tape and build up layers with a small piece of cereal box cardboard under it and a few layers of tape build up quickly.  1/16" can make a big difference... and when you're done, it peels right off. No harm, no foul. Measure the thickness if it helps and then peel your sideplate up and put a bit of toothpick, or other shimming material that thickness under the sideplate, glue it back and walla, you're done!

Sorry but you are not underspined, I get perfect flight out of .500 spine 30"s and 190 grains up front and I shoot 51#s at my 28.5" draw and my borders are a lot better performers than that Pearson. I believe you are dead on in spine and it is a form issue or just a little finger drag. 340's come on guys he is not shooting a 65# compound. Sorry but I hate to see poor advise given time and time again on carbon selection!! Keep working on your release, every 4 or 5 shots and a bad release is not terrible just don't let it happen when a nice buck is standing in front of ya!      Shawn

Thanks a lot Shawn. Your thread on carbon arrows is what's kept me from losing my mind with only 7 days til the Mississippi opener.

I'm feeling pretty confident after yesterday. I just need to stay in the right frame of mind while shooting, and I'll be slick.

That is the attitude to have, keep positive I am sure you will do fine!! Keep'em sharp and pick a spot and go kill something bud! Shawn

I have the same thing happen to me from time to time, and have narrowed it down to my release. Once I get good and warmed up, focusing on form and release, problem fixed.

Sounds like string plucking to me.Same thing happened to me a few years ago and I was plucking ever now and then.
