1: If I’m calculating total arrow weight and foc, do I worry about the feathers? I shoot 3, 5″ feather fletchings and cannot find what they weigh anywhere. I’m sure it’s not much.
I can’t imagine 3 feathers weighing more than about 5 or 6 grains. Just a guess.
5″ are 3.2 grs a piece. add a little glue and you may as well call it 10grs.

Yup. My grain scale shows the same weight for shield or parabolic cut.
The little digital scales are cheap, easy to use, and accurate. I’d say put the pencil and paper away and get a scale. They come in handy for lots of stuff.
