Monday I take deivery of a pristine Mauser P-38. I am going to reload for it but have no idea of what would work the best and be safe. Of course I don't want to hurt the pistol. Specifically I would like suggestions for bullet weight, OAL, Powder and such. Any other suggestions for this gun would be appreciated. I have on hand the following.....115 FMJ RN, 124 FMJ RN, various FMJ HP. The powders I have available are....... AA #7 ( 1st choice if applicable), HP-38, Universal, Unique, Bullseye and AA #5. Thank You !
