I want to thank everyone who replied.

Here is some more information on why I was looking for a SA 9.3. I currently have two 9.3x62's right now which has caused me to accumulate about 1000 assorted bullets in .366 caliber. I have a switch barrel built on a Kelbly Atlas short action with an extended Wyatt's mag box that gives me about 2.995" of usable length. This rifle is currently chambered in 338 Federal and I was thinking I would like to add a second barrel that might use my abundance of 9.3 bullets.

I am familiar with the 9.5x57 and it looks like if I keep it to the lighter bullets from 250 and lighter that the OAL should work through the extended mag box. I have a bunch of 232 gr Norma Oryx and Vulkans that should work.

Does anyone know if a 9.5x57 would work through that action with the Wyatts box?
