The ram rod has a hexagonal end .You cant buy them I had to make it. The original rod that comes with the gun has a round end and it is bushing against a hex bullet. The peanut oil in the lube raises the burn temperature. The stuff even works with smokeless powder. I have never had a bore to lead and you get a nice lube star. The only draw back is when you get it on your fingers you can't hold on to a bullet or anything else for that matter. You ought to try it Daryl. I think you will like it. I will probable only get a couple of hours tomorrow very early morning before it is to hot to be out in it. But I cant stand it any more. I HAVE TO FIRE THIS GUN.
