RE: Rattling antlers: recommendations please
Get yourself some real bone , if you have any shed's use them if not then get a good rattle bag.
Like davepjr71 said some have wooden dowels others have plastic but the real good rattle bag will have ceramic but those are hard to come by and very exspensive.
When using real shed antlers most hunters will remove the brow tine's so they won't hurt there thumbs , now I'm not sure who if any makes plastic antlers.
I know that the hard plastic will sound better than the wooden ones if your going with a rattle bag.
