Hi,
after some research i could`t found some representive topics about the Mavi Hawken but some about the Hege Uberti Hawken!
in March 1981 shortly after Hege Uberti introduce their new Top Model into the European Market the DWJ ( Deutsches Waffen Journal = German Weapon Journal) print a report about the new famous Hawken in their Journal. Among other things like the 1 to 1 authenticity nearly to the original Hawken Rifles a test was done by Helmuth Mohr/ Mayen a skilled Blackpowder Shooter and Gunsmith.
Helmuth tested all new BP Rifles at this time, Tryon, Wesson e.g.he tuned them a little bit and shows the results.
i will pic here two photocopys from the DWJ
hope that is is not to bad to realize it.
the first ist the report and the seond pic ist the promotion page .
Due to the text information about the test of shooting" Helmuth filed of 0.08 inch from the frontsight and drove it a bit to the right.
Point of aim at the 6 on six o`clock.
Charge:70grs. Dynamite Nobel Nr 1
Roundball: 0.520
Patch: Ox Yoke 0.20 inch
13 shoots offhand practice
