This is a great resource if you guys haven't tried it.
You can download it here;
Stu Miller's Dynamic Spine Calculator download page
Or you can use it on the 3 Rivers Archery site
So I'm working up to my old shooting weight and just didn't quite want to shoot 55-60# for the upcoming hunt seasons.
I settled on 50# and can shoot that with either my Morrison or Dryad ILF risers and my Inno limbs. ...30" draw.
So I plugged everything into Stus calculator and it came up with Beman MFX 340s at 31" with a 75gr insert, 150gr head- total weight 586gr. Dynamic Spine for bow came in at 60.4, arrow 63.2...you want these values to be within 2 or 3#.
On the Stu calculator a couple tips; crucial you enter the info correctly....READ the instructions. Even something like the strike plate being off by a sixteenth or your actual DL off by 1/4" will give you a bad reading.
So I bare shafted that arrow yesterday....Bingo, shoots right with my fletched arrows at 10,15,20yds.
Assuming you have decent form...and enter info correctly....I've found that Calculator to be right on the money. A time saver for sure when experimenting with different arrow configurations
