What is the O.A.L. for a factory 9.3x62 with 286 RNSP projectile ?

I've got reloading components but won't spend money on a box of factory loads (if I could find any ! as I live on the edge of the outback). The rifle is still at the gunsmiths and he needs some loaded rounds to check smooth feeding and to regulated the standing rear leaves.

Action is a columbian FN Mauser 98.

Cheers
