anybody useing a shotgun powder for reloading the 223?ive been useing 4198 and have had good luck with it but im looking for a cheaper way.
It depends on the type of load you are trying to achieve:
If you are looking for a cheaper way to load for an AR, you are looking the wrong direction. You would need to look for some of the surplus
rifle powders from some of the surplus sellers.
If you are looking for a cheaper way to load for bolt action rifle for plinking, then yes, lots of shotgun powders will work with cast bullets. I have even heard good reports on the new Trailboss powder.
If you are looking for a way to load some subsonic rounds, there are some shotgun powders that will work, but there are some pistol powders that will work even better. Now you get into case sensitivity, fillers, etc.
It would be easier to answer the question if we have more information on what type of gun you are loading for, the type of load you want, and what "cheaper" means to you.
