I found out from the farrier my wife uses to shoe her horse that horseshoe nails come in many different sizes. He gave me a few to try. The higher the number, the thicker & longer the nail. I first started messing with #5's and they were too soft & thin, but they are great for doing micro-serrations on the edge of a point. I like the # 8's best. They are the size used on them big-footed draft horses so the have to be strong and long. I checked an online catalog http:// www .westernranchsupply.com/body.php3?cat_id=5&sub_id=31
and there are nails available bigger than that, the farrier just didn't have any on his truck.
Hope this helps.
