H4895 will always be on my shelf. It has one of the largest charge weight/velocity windows I'm aware of. Great economy when downloaded to 60% of max for plinking and one of the only powders Im aware of that can do this. Suitable for "Youth loads" as well as full power loads and versitile across many cartridges from short action to magnum. It may not always produce the highest velocity for a given cartridge but I'm not aware of a more versitile powder on the market.
