Gentlemen,

I had the luck to obtain last week a Gustav Genschow & Co. AG in 10,75 x 57 on a 98 system basis.

I tried Daryl_S excellent advice about enlarging case diameter with very good results.

As you stated correctly the 8x57 and 9,3x57 are much too short, so I will try & test the cheap Prvi Partisan in 8x60S as basic cartridge cases.

CH dies has a 10,75x57 MANNLICHER die set, my current version of the Quickload ballistic program displays the cartridge dimensions.

bullets:
- Degol makes a fine 300grs SP (almost a rounded flat point)
- of course the Woodleigh 347grs SPRN
- Reichenberg Homogenous Deformation Bullet (HDB)in 280grs
- Delsing ?

best regards
Rolf
