No ... the problem was that I´d been using a bullet that was too stubby. A longer, more elongated bullet entered as far as the rifling and the COAL is now the standard 50mm. AND .. I´ve now got a BP powder dispenser and can reproduce an exact load that allows the bullet to be seated to the correct depth every time. I got every round within a 10 inch square at 50 metres today at the range (which is a great improvement) but have to aim at a target hung 10 inches below it. So will now take the short Werder over to the 100 metre range. If the sights are then still much too high, I´ll experiment with a lower powder charge and fill up the case with semolina. I like the Werder much more than the Mauser 71 although it´s such a nice looking carbine ... But still ... think it´s for the chop.
