Most people, myself included, use a fast pistol or shotgun powder (small charge) and fill the rest up with cream of wheat then plug the case mouth with a wad of some sort. (disclaimer- NEVER USE A PISTOL OR SHOTGUN POWDER FOR RIFLE LOADS UNDER A BULLET UNLESS YOU WANT TO SEE YOUR RIFLE BLOW UP. THIS METHOD IS FOR CASE FORMING ONLY AND NOT TO BE USED IN CONJUNCTION WITH A BULLET OF ANY KIND) I figure you already know that Jake but there are those that come on here that may not know that little problem so thought it best to write out that disclaimer.
