Re: 6.8spc -compressing powder
If you are using load data from a modern manual (and you would have to be with the 6.8) a compressed charge will be just fine. Some of my loads quote 105% load density and you will certainly get some serious crunching sounds when seating the bullet. Sometimes you even have to be careful about seating too quickly as you can damage the case.
