I'm kind of in the same boat. I started buying a certain brand powder, bullets that were the same through a local store. When the shelves were hit hard and not much to choose from it made me think. I should have several different loads with different powders, bullet types and weights worked up in case the trusty old components are not available from time to time. I generally like to stick with what I know works for me. Experimenting with different components may also help me find something I like better.
