So I purchased a Grey Wolf to add to the collection. My issue is reloading the 300wsm..Lee dies are brand new (never used Lee before). Resized once shot Federal ammo. So I have the bolt sliding free (extractor & pin removed) Place the brass into the chamber and the bolt closes hard. Trying to "move" the shoulder back but there is no adjustment beyond the die touching (firmly) the shell holder. Has anyone had the bottom of the die shaved 1-2 thousands to allow the case to travel up into the die more ? I also notice you can by shell holders that are different thickness so a thinner shell holder will allow the case to enter further into the die and achieve the same thing. Correct ? All other calibers I reload are fine and I have never had these issues. I understand once shot ammo is the perfect chamber size but that means changing dies now to neck only..right?
