This is my second year drawing multi season so i decided if im gonna keep putting in for it i'm going to get a better bow. I bought a diamond Black Ice for 200 bucks from my cousin all set up with these fancy fiber optic sights and camo quiver whisker biscuit etc all new stuff to me. Last season I was using my uncles old martin and had some beman ICS hunter 400's 29 inch @ 8.4 GPI with 100 grain sonic heads (gear that I inherited as well, my entire family bowhunts and I didn't really know a whole lot about bowhunting). So I hunted all season with this old bow and wasn't very happy with it. When i got my new bow I had it re-set to 30 inch draw length and have been using the same arrows at a new 70lb draw. I've got it sighted in and gapped 20, 30, 40, and 50. Last night I realized that my arrows were about 50 grains short of the legal minimum D:. So, I need new arrows and was wondering whether I should get 300's or 340's. What would work better for hunting deer? do you want to go as light as possible? My apologies for being so clueless all i know is that its a sweet bow and i'm shooting tiny groups with it but i can't hunt with my arrows now lol.
