Reducing a .300 WSM to a 7mm Rem-SAUM die w/a long neck

  • Right, The Skip Otto Die will move the shoulder back in a series of steps on any cartridge that is the body diameter of the .308 Win, or BR or .30-06.  It doesn't work when moving shoulders back on .223 or the like, cases get fat, because of no body support.  It also doesn't fit any of the belted or non belted Mag Cases.

    It is as it was advertised, A "BR shoulder set back Die".  Very general and non cartridge specific.  Yours looks as if it were the cadillac for it's intended purpose. And with a set of reamer or chamber prints, you could probably build a specific die for anyones wildcatting needs.  In this case a guy wants to use Norma .300 WSM brass in his Remington 7mm SAUM, rather than the Remington (less than desireable) brass.

    I too was thinking about Run-Out...    These dies are for forming cases, lots of brass gets moved.  When the case is fired in the chamber, more brass gets moved...  Right out to the exact dimensions of the chamber.  From here on out that case never goes back into the case forming die... It is formed and now only needs to go into a shoulder bump die, or full body die...  If the chamber is straight, wouldn't 65,000 cup take any runout out of the brass?

    Yes it will, but since I have to do about 500 cases, I would hate to waste the first firing just to straighten out cases, not to mention half my barrel life!
