Hey, I'm looking to trade for a crossbow so I can introduce my son to deer hunting. I found one on craigslist, it's a Barnett Ranger recurve style. I'm a noob when it comes to crossbows and wanted to get opinions of the people who use them on a more frequent basis. It can't be a high end, the guy is only asking $45 or trade for it. I found specs that it's 150# pull, so I figure it's got enough to kill out to 20-30yds. I was gonna look at it and make sure the limbs look okay, shoot it, then see if he'll make the trade. Any other tips?
