Wow. Got 100 from the store it said 100 grain arrows and thanks a lot the numbers on the side are 051815
For deer hunting you usually want something in the 400 -- 430 range is were people around I live like. Some like it heavier, I'm shooting about 430 right now with my new arrows. Trying to get as close to 420 as I can or a littler lighter.
most arrows should have a grains per inch number on the side. I think my xt hunters are 8.2 gpi and its says it right on the arrow. my total arrow weight its just shy of 400 grains (like 390ish), but I only have like a 60 pound draw.
