Q: 9.3x62 C.O.A.L?

[308BAR]

I need help I'm trying to determine OAL of this cartridge in my 9.3x62 Husky. I made a split case and placed a 250 gr TSX bullet in the mouth of the case. With the test bullet seated in my split case, I insert the round into the chamber. The rifling should push the bullet deeper into the case. Then I carefully extract the round without disturbing the bullet.

When I pulled it out it didn't seem seated at all, it measured 3.598":

As you could see by the photo it not even at the first ring. Anyone have any ideas if this is correct? At this length if I follow the reloading instructions to back it off 0.050" from the rifling it probably would not fit in my magazine or eject properly. Any insight into this would be great. Thanks in advance.

*edit* P.S. Should I just seat it until in just fits in the magazine and ejects properly? Will it have any effect on accuracy being so far from the lands?

oal is 3.290", as it was designed to fit into military M98 actions originally in 8x57.

The CIP specs give it a very long tapered throat, like most european 7x57's, and you will not be able to get anywhere near teh lands with a bullet.

As you say, just load them 50-60 thou shorter than your magazine and hope for the best.

Using the good old 'wooden dowel down the barrel' method of determining OAL, I've come up with these distances off the lands in my 9.3X62

Speer 270 gr - 3.30"

Nosler Partition 286 gr - 3.44"

Prvi Partizan 286 gr - 3.33"

I just load to an OAL of 3.28-3.29" for proper magazine fit and call it good.

With the exception of the Prvi Partizan bullets, I'm getting very good accuracy(sub moa) with Speers, Noslers and Hornadys.

I've read in a number of sources that a long throat is standard in the 9.3X62.

Also, I never had much luck measuring OAL by the method you described. The rifling has a tendency to grab the bullet and hold it.
