Need some help with arrow tuning (pic)

[Arrow4Christ]

I normally use 200grain points and was planning on using a 200 grain Snuffer this year. I bareshafted my arrows and they turned up weak (I'm Left Handed remember, so arrow left is weak). They should be grouping right together becuase I have some duck tape wrapped around the back of my bareshaft that weighs the same as the 4 vanes on the back of my arrow. My bareshaft was hitting about where you see the red X in this pic. I put on a 125 grain point and cut one inch off the shaft. I also stiffened up my plunger pressure and moved it out some. This pic is where the arrows now group. I would like some advice on what you think I should do? Should I switch broadheads, or is there another way? Perfect arrow flight is very important to me, so I'll change if I have to. Thanks,
Craig

Sounds like you made more than one change at a time. Only one change at a time is recomended. Check out the segment about tuning on OL Adcocks site.

Jerry,
No, I bareshafted it with the 125grain point BEFORE I cut the inch off. Thanks,

When you say you bareshaft tuned with a 125 grain point after you cut an inch off I think you should stay with that 200 grain tip because you made the arrow stiffer when you cut it. Also Jerry is right make one move at a time.

deerslayer,
I shot it with the 125 grain tip BEFORE I cut the inch off and AFTER I cut the inch off. I've done it both ways. I cut it because the arrows were hitting to the left, which for a lefty means weak.As you can see, they still are a little. Thanks,
Craig

Craig, you also mentioned stiffening your plunger, that is why I say one change at a time. I understood the 125 point and all. Every little thing you do makes a difference. Just trying to help.

Jerry,
Thanks,
I guess I worded my original post incorrectly, sorry. I moved out the plunger first thing, too weak. I then stiffened the plunger, again too weak. At this point I put on the 125 grain point. Still too weak. I cut off the shaft and the result is what you see in the picture.
BTW I ended up needing to cut another 1/4" off the shaft to make it fly right. My bareshaft now hits dead on with perfect alignment at 40 yards. Thanks for the help everyone!

Craig, Glad you got it right now. Jerry
