That's awesome news. I'm building a 18" 308 now off a Kelbly Atlas. This will be tried out for sure.

It is compressed, but no pressure sign. Col was 2.725.

Any crimp used?

No sir.

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.

 

[just_jon]

Powder charge / case capacity x powder bulk density. Or you can put your calculator away and refer to the Nosler manual or website.

Referring to Nosler data is easiest.

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?

Just go on line. No purchase necessary.
