Hello, I've been a member for a some time now but usually just read! However I now have some questions. I just bought my first crossbow, Not high priced one but seems like a good one. It's the Horton HD150. It will be used to hunt Kentucky whitetails ( the four legged kind). Now after all that her's my qustions. Horton says use 20" bolts, what about shorter? Like 17.5"? Is there any difference in broadheads, between regular bow and crossbow? Will my trusted Muzzy 4 blades work? How are the crossbow bolts listed?? Like my carbon arrows are 400's. What size should I use? Of course Horton recommends thier brand. Well that's all for now. Thanks.
