My wife is only shooting about 40#'s. I have her shooting 90 grain Muzzy's and a 2018 arrow. Her range limit will only be 20 yds max, but she should have plenty of punch with that combo. I say keep it as heavy as possible and keep the shots close.

Two years ago she shot a doe at 8 yards with a carbon arrow and a 75 grain expandable. It got the job done but I don't think it would of been to affective much farther away!
