Why does my 125 gr.Magnus 4 blade drop 3" from my point of impact lower than my 145 gr. field points? I am trying to learn 2 or 4 blade heads. ( I've only used 3 wensel woodies or snuffers). so.. when I shot @ my target in the backyard (15 yds) the bh had a hump in the flight and DROPPED !! No Matter the how the blade was positioned, Flat-vertical-45 etc..What the bleep isgoin on?

Sounds like it may be nock height, a little to high.

It is probably a tuning issue as L82HUNT says,meaning nocking point height.A fetched field point arrow may not show slight problems where a broadhead will magnify a tuning issue.When the broadhead impacts with the field point,you are tuned.Go to bowmaker.net and read the bow tuning information.You may only need to move the nocking point a small fraction,1/16" or less.

Could it REALLY be THAT simple?? I don't have much hair and it's  rapidly falling out over this!! Was trying to bag a robber coon last night. Good thing I never got a shot!! I'll definitely try that!! I get back to you after I mow the yard and change nock height..  

WELL Boys' your partly right. Nock was a little high. Major problem was shooting a arra that was not mine--Same make, same lenght,Buut had 3x5" fletch.Mine are 3x4,this one had a 9" capwrap .Mine don't..Mine have been tuned to my bow.Apparently this one isn't.Took a Bh test to reveal that fact. Funny how one subtle change can have such a HUGE impact..Now field points and BH Have same POI.Gotta refletch some...LOL. Thank's to ALL for the help.. Let that little trash nabber come back tonite BWAAA HAHAHA.  

Good deal glad you got it figured out.  

Gandgolf, great minds must think alike! I just snuffed a chicken killin coon up here in Montana... They are tough little buggers.

Pick a spot.

For me broadheads are the final step in arrow tuning. It doesn't take much to make a "perfectly" tuned arrow with a practice point to do weird things when a broadhea is  attached....especially a wide two blade.

I never would've believed.. No kiddin'.. IN GOD I TRUST
