making a 308 from a 30-06 case

[wbrewski]

Has anyone tried this and is there any recipes for this?  I have a very large quantity of 30-06 cases.

Should be real easy to do.  Determine the length to cut the case first.  Run it through the sizer die, make final length corrections after that.  Very similar process to making 300BLK from 5.56 NATO.  You're only going from 7.62x63 to 7.62x51.

Hmmm... this could be a nice experiment. I think I have some 30-06 shells lying around.

Don't they have different rim and extractor groove dimensions?

 While the base dimensions are the same, the shoulders are 2.5 deg. different. Spend a few bucks and get some .308 dies and some 1x-fired LC cases. I wouldn't do it. My face is too important.

Hmmmmm !

Got a bunch also. 270 Win is another source for 308 brass if you are going to size it.

  With once fired 308 brass so redly available , why bother .

 

 Another thread for the reloading section.

  At one time, I made a few thousand 300 savage cases out of '06.

  All that required is a file/trim die.

Running the cut -06 case through the .308 Win sizer die makes a completely new shoulder on it - for .308 Win.

  After case forming ,the case will be fire formed after the first firing & as long as it doesn't read 30'06 on the base , you will never know it was one by looking at it . Annealing will make the case last longer for reloading , of course.
