the special thing about this drilling is the rifle cartridge, the 11x65r Collath. we dont know much about it and the books have it allways wrong

COTW call it a 10,75x65R, dont have a pic

again but here with a pic and we thought it before: its the 10,75x65R Gründig
its a mayor mistake because the 10,75 Gründig is the rimmed version of the 10,75x68

its not the first time heard about a super rare 10,75x65R Collath and I am sure it never exist.
this is the 11x65R, dont they think Collath could not distinguish between 10,75 and 11mm

and loaded with a Tesco Bullet, available in 9,3mm, 11,15, 11.5 but not in 10,75

the mysterious 11x65R must be the common 11,15x65R LK loaded with nitro for black and the 11,15mm Tesco bullet and I will try to confirm this. BTW, the Collath catalog also give the same 3 gramm Rottweil powder No.5 load we find with other NfB loads for the 11,15x65R
