Caliber is 7,92 x 57 (often called 8x57). I don`t know what this match is in the USA, we shot 20 rounds at 100 metres, for fun we shot at 200 or 300 metres, too, this is the longest distance in our range here, it`s a former army range.
Between people there is today no difference, but you can see 20 years after the fall of the iron curtain still houses in the east who are more a ruin than a house. Some parts of ownership are not clear so nobody could do anything at the houses. But it will be better from year to year.
