I had an opportunity to speak to Helmut/Herbert in Bessemer Alabama today. Quite a heavy accent. My reason was to get an owners manual for my 470E Merkel SxS. I mentioned the "doubling" issue and he said the majority of the problem is operator error. The right barrel/ front trigger must be fired first. The second barrel must be fired in 10-15 seconds because the heat from the right barrel with change the poi for the left barrel if you wait too long. The rifle is regulated to 50 meters with a 300 grain bullet. He also explained the German Proof Mark code. Just reporting what I was told today.
