Compressed loads with long bullets

[Klem]

I agree with Happy here, but I still think we need to be mindful. Especially if doing it for the first time, or loading for long term storage (e.g., prepping). I use compressed loads in other calibres all the time, using standard tricks to increase density like vibrating and drop tubes. After 103% full which is technically already compressed that's when it starts to crunch, and in a small case like the Grendel it doesn't take much more before it starts to get impossible.
