Gentlemen,

are there any forum members who have advice/experience about the cartridge 10,75 x 57 ?

I found meagre information
- "Cartridges of the World" for ballistics
- CH die shop offers a die set for the 10,75 x 57 Mannlicher
- case forming should be no problem (basic 8x57 IS or 9,3x57 from Norma)
- bullets from Woodleigh 347grs / Degol in 300grs / Reichenberg in 280grs
- Quickload program lists caliber (with a drawing of the dimensions)

Can anyone tell me whether it is advisable to make headspace with the small neck of the cartridge or the case mouth?
COTW mentiones that headspace can be a problem with a small shoulder like in the 400 Brown Whelen and the 10,75x57.

Any information would be greatly appreciated!

best regards
Rolf
