Not in Germany but in Aden we (not the RAF Regt) were still issued with the Lee Enfield 303 of WW2 vintage with ammunition. It was quite common when filling the magazine for some of the rounds to separate leaving the pointy end in one hand and the explosive end in tóther. Just as well we had TTN and friends buzzing around at the time.
One of the Sgts I used to work with was out there and he told me when he was on guard as a lowly LAC he was told if anything happened to let off a round and the troops would come a running, he said something about dropping his rifle or similar and a round being discharged, a solitary dog barking was the result and when relieved no one would believe he had fired a round off until they checked his rifle barrel. He did mention it was most perturbing as he could have been fighting off hoards of Arabs and no one else would know or come to his aid.
