I think thou wouldst regret using anything but the full length '98 (8 3/4'') for the 9.3x62 (although it IS shorter than the old '06). Remember those thousands of Columbian FN's with the gouge ground out of the front receiver to accept the '06 in stripper clips? Jesse O can tell you if your barrel profile has sufficient meat for the 9.3x57 for one thing, the other is body and shoulder dimensions are different 7x57 vs 9.3x57, they are two different animals. You need to get the drawings and compare, I'm just guessing that you may have to set her back a turn and cut a clean chamber. Might be cheaper to get a new 9.3 tube and sell the 7x57 tube. Half fast opinion.
