Yeah the super low case fill is the main reason to perhaps steer clear of it. But it does work. Worked beautifully in 300blk in fact and had an ES of 7fps with 225gr ELD's. But that's in a much smaller case that obviously gets packed out nicely. Again, it just wasn't as quiet as the faster burning flake powders (which you would probably also be able to double charge a 308 with, if not paying attention).
