I think I'll bite the bullet and go to a crossbow this year. My shoulder bothers me more each year, and I've lost my practice range since they developed the baby farm behind the house. What are the do's and don'ts with a cross bow? I'm looking at a 10 point, Wicked Ridge RDX400, or the Titan M1 Rope sled. I know nothing about crossbows, never shot one. Any tips, thoughts, or advice would be greatly appreciated.
