All the data I have right now for the .30 Luger uses a 93 grain FMJ bullet......however, nobody 
makes a 93 grain FMJ bullet anymore!

  I see that there are some 85-86 grain bullets out there for the .30 Mauser.....could I use these in the .30 Luger?  How would I go about figuring out powder charges, ect. for this safely?  Thanks in advance.........
