Hello All,

I have a remongton 700 ADL Synthetic that needs to be rebarreled.  I think I would like to go over .30 caliber, but am not quite sure I want a .358.

I did some think and came to the conclusion that necking the .308 case up to 8mm would be absolutely ideal for my needs.  I know i am not the first guy to have this idea, but have been unable to find any reference to this cartridge anywhere.

If anybody knows where I can find dies, loading data, etc. or has experience with this cartridge I would appreciate the input.

Hi Rummer,
  I'm not sure, but Redding may have dies without doing a custom run. As for data, I'll do some looking also. As for an option, contacting a powder or bullet mfg'r and ask the for starting loads.

HEy Rummer:  I have seen several articles on the .338-08 wildcat.   This is very close to your idea for an .323-08  (i.e. 8mm-08) and the data should be very close.  You could certainly use it for starters.  THere are some very juicy 8mm bullets out there now.  NOsler makes a 200 grain Partition and a 180 grain BT.  I shoot a lot of military surplus 8x57, but have never messed with the idea of this caliber on a .308 case.  

You said you thought you wanted something bigger than .30 cal and thought 8mm would be just right for your needs.  Just out of curiousity, what are your "needs"?

Rummer:  this is just from my personal perspective, but I wonder why you would want to 'download' the 8mm by placing it in a shorter case.  The 308 is a 7.62x51mm round - the 8mm is a 8x57mm round.  

I do not know what the original caliber of your Rem 700 was but, if it is a long action and you are looking at an 8mm bore, I would just go with the 8x57 or a longer 8mm even.  If the Rem is a short action it may still be able to handle the 57 mm length cartridge, but I would check with a gunsmith on that one or possibly even the Remington factory (they are in NY, in Ilion, in the 315 area code).  Oh, BTW, The 2004 Remington Classic is chambered for the 8x57.  I wonder how that action compares to yours????  HTH.  Mikey.
