Many of you are setting up for target leagues and such presently and the question of wrap weight has come up. So, here is the gist of our wrap weights so you can determine how it will affect your setup.
Standard wraps weigh 1.1 grains per square inch
Reflective wraps weigh 1.6 grains per square inch
Double Doggs weigh 0.5 grains per square inch
So, if you take the area of your wrap and multiply by the weight per square inch you will get the total weight.
For example. If you shoot a 1 x 7 wrap multiply 1 x 7 (=7) and then 7 x 1.1 for standard wraps giving you 7.7 total grains.
I hope this helps...and as always, let us know if we can be of any assistance to you.
