other than drawing back and holding till you release or have medical problems on using a re curve or a compound there any real advantage to a cross bow? speed seems close in most cases as a compound. they shoot flatter ? they good to 30 - 40 yards i can't use a compound any more. arthritis in my shoulder and right hand . thinking of getting a starter cross bow seen some $200.00 or less that will shoot 270 to 300 fps . i can't afford much more than that.
Looks like everything has been said so this might be a bit repetitious. I have a Horton Supermag which is a 150lb pull and shoots a 20-inch bolt at about 260fps. I have killed maybe 30 deer with this thing over the years.
If you have shoulder problems or arthritis problems, cocking the bow will be a problem. As mentioned above, you can buy a cocking mechanism which will take care of that. BassPro sells them, I believe.
Having the bow cocked when a deer comes by is definitely an advantage to pulling back a compound. Much less movement since all you have to do is sight-in and shoot. If you have a scope on the crossbow, it's fairly easy to place the shot in the desired spot out to 30-yards.
All the above really applies to shooting out of a tree stand or maybe a ground blind. I have always used mine in a climbing tree stand and a lot of the shots are less than 20-feet away. If I had to still-hunt, I think I would put the old crossbow up in the attic and forget about it. I would say that at least 75 percent of the deer I have killed with the crossbow have been does which is fine if you are just after some venison.
If you know someone who has one, you should check it out and make sure that cocking it won't be a problem for you. Shoot a few bolts to make sure you like what you see. Never dry-fire one.
The only other advantage I can see over a compound is that it doesn't take any skill to be effective with a crossbow. Once you have it sighted in properly, you can just about pick it up from year to year and go hunting. I can shoot three or four shots on the last day of September and be pretty well assured that I'll have at least a doe by the end of the first week of October.
