sighting in for new arrows

[h5c5o5]

Hey everybody

I recently upgraded my arrows from some crappy 430 grain arrows that broke/were lost to some 560 grain arrows that hopefully wont break at least. I sighted in my twenty yard pin by just moving the entire sight up and down. Prior to switching arrows all my pins were sighted in beautifully.

Do I need to sight in the individual pins for 30, 40 , 50 etc or will those pins now be accurate due to the sighting in of the 20 yard pin?
I worry that because the arrow weight has changed the trajectory of the arrow will have changed as well but I do not know if this means those other pins are no longer accurate.

Thanks
Henry

What type of arrows are we talking about.

[h5c5o5]

The new ones are the Easton axis 300 at 11.5 grains per inch (http://www.eastonarchery.com/arrows/axis-realtree/0/2). 100 grain field tip / slick trick standard broad head, 20 grain insert, cut for a 30.5 inch draw length.

The older arrows were gold tip velocities I believe though I cant remember anything else about them at the moment.

The only real way to know is to hit the range and find out. I recently went to a heavier arrow and stiffer spine and after adjusting my sight at 20 yards I had to move the sixty pin and it was ready to go...

Practice... often times the small change in weight  will not effect your shooting if your a new shooter. If you shoot very tight groops then some adjustment will be needed.

From 430 to 560, yes each pin needs to be resighted......absolutely.  Also, I always sight in the 40 yard pin dead center of the sight body and then gang adjust so the 40 is dead on.....then reset 20, 30, 50 and 60 yard pins.

You may find depending on the bow and riser design, and sight, that you may not get a 60 with that heavy of arrow.

your gonna have some big gaps.

I think i stated my position poorly.  What i ment to say is Yes the impact will be different. UNLESS you are NOT shooting nice tight groups BEFORE the change in arrows you may not notice the different in impact very much. If you are dropping 3 shots in the size of a quarter to half dollar at 20 and are doing the same with the new arrows then yes refigure the pins for the longer yardages. If your not dropping nice tight goups at 20 yards then get your 20 dialed in tight then move on to the other pins.

If your groups are not tight then your 2 patterns for the 2 different arrows will overlap making it harder to adjust your pins... Hopefully that claifies my point.

Like others have said go shoot it and adjust acordingly. I ran your arrows into on target and just a round number of 30" arrow comes out at aprox 492grains. Where are you getting the extra weight?

I was wondering that also I had the same arrows and they came out to 580ish but had a 100gr insert and 125gr broadheads.

This is what I like to do as well and what I've been doing this weekend with my new arrows.  I waited til after my 3d season so I would burn up my old arrows first.
