I haven't really shot a bow since boy scouts and wanted to get into bow hunting. I picked up a used Bear magnum bow from someone the other day for $50. I had one of my coworkers look at it and said it was in shootable condition, string needed a good waxing but wasn't frayed or anything. I shot it a few times today and without a peepsite and getting a grouping of 4 arrows in a circle about the size of a paper plate at about 15 yards. It seems loud to me compared to the one I borrowed from my brother-in-law and I think I found out why. The metal bracket that holds the top cam on is bent a little and when I draw the bow the cam turns kind of crooked. I figure that is causing the noise since it came from the top of the bow. I know I should have this looked at and fixed but can I keep shooting it like this? Is there a place online to look up parts for this so I know what the part will cost for when I get it fixed? Also, there is no tag or markings on the bow. I am calling it a Bear Magnum only from being told by the previous owner that it was one. Thanks for any info anyone can give me.
