Okay, went by dads house and he has some Easton 2018 game getters he hasn't used for years, and they have 145 grain tips on them. According to the easton charts this should work? Arrows are 29" long.
Too stiff. Trust me. But they will fly out of it. I use a 2018 with 125tip from a 54lb high performance longbow.
Here is a correct chart to use. You use a easton chart, you will be too stiff every time.
