target question

[iowabow]

Starting target practicing from the deer stand yesterday morning.  I noticed that a had better groups at 20 yards than than 10 yards.  Why would I group better at 20 yards? I thought it might be because it is more of a straight down angle and therefore an unusual stance.  What do you guys think.

Keep your shoulders square and bend at the waist and it should  make  no difference,people tend to drop the bow arm to line up the shot. It also depends on how high you are I never hunt over 12/15 feet at the highest.

Thanks pappy I will go and give that a try

 Or, your arrows aren't tuned real tight and it takes that far for them to stabilize real good.

Ok good point I just rebuilt my bow so the poundage did change.  I will have use a stronger spine.  So if I fix my stance and arrow issue that should help.

Update
I grab a group of heavier spined arrows and focused on stance and the groups are now real tight.  I am dialed in now and ready.   Now if if somehow we could make oct. 1 st tomorrow. Thanks for the help.
