I'm interested in hearing what powders are considered "must have" on your shelf for working up loads. Also, what cartridges you would consider them useful for. We know that there is no such thing as a universal powder but some tend to be our go-to choices to at least try. For me four powders are H-4831SC, IMR-4350, IMR-4895, and BL-C(2). With these four choices I feel like I could get a test load for a wide range of cartridges. Although, they may not end up being my optimum choice. That said my shelf has a range of others, but these I always make sure that I try to keep on-hand.
