It is just a 338-06. I use standard RCBS dies.
Its on a Rem 700 action that has a long mag box and even though I didn't ask for it , it has a very long throat, but it doesn't hurt the way it shoots.
Mine is 3 years old, fired about 7-800 rounds and I still havn't full length resized yet. I'm still using the same 100 Norma cases, but everyone seems to think these are warm loads.
