That's freaking awesome
 
Steve's Opening Reminders:

We recommend looking for a powder showing fairly high load density for similar weight bullets, but not compressed. We like to use powders that show a 90-95% load density with conventional bullets of the same weight. This will leave some room for the longer copper bullet and for the lower pressure possibly needing a bit more powder to get to pressure.

I reload but do not understand how to 'calculate' this 90-95% load density for a perticular caliber. Say 30-06 and 7mm Magnum? Is there a formula or is it a hit-or-miss trial? Please discuss.
 
Powder charge / case capacity x powder bulk density. Or you can put your calculator away and refer to the Nosler manual or website.
Dog gone it. You just made me buy a new Nosler manual (9). I have new Sierra and Honrady but my Nosler is #1 1976. It will be for sale on ebay after I get my new one.
However, where does one get the 'powder bulk density' information?
