thank you kari, I will keep this in mind but the reloading stuff comes first. Johannsen list the 414 supermag brass and I hope they realy have it. if not I have to do the hard way and rework 7,62x39 brass. the 414 supermag brass is not available in the united states just know(to my knowledge) so I hope they sit on old stock.
for reloading I will take a 41 Mag Lee die set. the only bullets available here are .41 mag 210 grains JHP bullet's. Sierra, Speer, Remington, Hornady - all the same stuff. dont think this will be a hunting bullet but for paper enough.
when having time next week I will made a resizing die for resize .410 bullets down to .407.

to become independent once I will try to make my own bullets. 9mm parabellum brass seems to be a good aspirant for this job.

I weigh the rifle and its 3850 gramm but had swear before its over 5000 gramm.
if anyone is interested how to dissamble there is video about the Winchester M 1907 that's maybe also true for the M 1910:
