I will be honest with you! Arrows from CB for all their power they fall fast. They're at their best out to 30 yds. It always depends on the deer. Are they calm and feeding, if so and you have the right CB scope 35 maybe 40 yds. is max! Heavy as in arrow or CB? Weight or power pounds? What type of CB do you want? How heavy in weight do you want to tote? Excals recurvesare lighter than compounds. Prices from el cheapo's up to couple of grand. Lets talk!
