Load for Ruger Old Army
My new Ruger Old Army arrived today and I'm wondering about a possible load. The Ruger manual calls for a .457 round ball. Is it possible to use a Lyman .45 caliber 230 grain roundnose, flatbase bullet? It is the old Lyman 452374 which I have plenty of. It mikes at .452-.454, depending on whether or not it is sized. They would have to be tapped in with a small plastic mallet because the bullet won't fit under the rammer. Would this smaller diameter cause a gas seal problem?
