Title: sighting in for new arrows
Post by: h5c5o5 on August 09, 2012, 11:21:15 AM: 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

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

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

Post by: Special T on August 09, 2012, 02:05:40 PM: 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.

Post by: Button Nubbs on August 09, 2012, 07:05:19 PM: I was wondering that also I had the same arrows and they came out to 580ish but had a 100gr insert and 125gr broadheads. :dunno:

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.
