This gun was made with a end cap made of antler, and the sides of the end cap actually flared out a bit. It was not belled out through the entire arc, but looked more like an oval, or football shaped end cap when viewed from the muzzle. Yes, he left enough of the texture of the antler for you to recognize what it was. This one I saw was in the white. You can stain or color them, too. It added a little weight to the muzzle of the gun, in the oval configuration, added a kind of racy look to the muzzle of the gun, although nothing like the Weatherby end caps with the severe tapered joining, and made it easy to feel your hand getting to the muzzle of the barrel when you dropped the gun to the grown for a fast reload. I was impressed, and considered trying to use the ide in a gun, until I worked with antler to make some knife handles. I don't know if I have the patience to make an end cap out of the stuff! The smell will drive me out of the shop, too.
