9.3x62 O.A.L.
      #107209 - 11/06/08 10:01 PM

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

I would not worry about factory ammo OAL for a modern custom gun. Your head throat / lead & magazine length are the critical factors that should determine OAL. In other words, the bullet should be seated about 0.030 inch from rifling & still fit the magazine. If that makes it too long, you should still be able to get it in the magazine easily for smooth loading.

My Simson rifle was made before 1912 according to the proof marks.

My loads' OALs are
* Lapua Mega 285 gr RN 3.229 inch
* Norma 286 gr RN 3.244 inch
* Woodleigh 320 gr RN 3.180 inch - this is a fatter & longer bullet that needs to be seated deeper in the case. The ogive is further forward & hence the OAL has to be shorter in order to clear the rifling by 0.030 inch.

I have made up dummy rounds with bullets in empty cases for seating die set up. I used 30'06 cases & they feed fine!! You could just load up dummies in the Norma cases & check the lead / seating depth.

Hope this helps. I would be interested in what you decide. Good luck.

GS HV230gr - 83,00 mm

P.S. Factory OAL is 83.60mm aka 3.291":

I presume this is not a RN bullet. The original post asked about RN bullets.

Edited - I can now see the picture in my office computer but not the home one as the safety net blocks such pics.

This clearly shows that your magazine has ample space & you will need to check the rifling / lead. The gunsmith should be able to do that before sending you the rifle. Just send him the cases & bullets. Good luck.

Thanks for all that info guys. I don't have the rifle with me to check seating depth off the lands or magazine length as it (the rifle) is still with the Gunsmith. I will have to do all that later.

This info will certainly help me load up some rounds for him to check the feeding. Any aberations in regulation can no doubt be adjusted later.

FYI. The barrel is a pre-chambered Lothar Walther.
