9.3-338

Has anyone ever heard of a 338 win mag case being necked up to 0.366 (9.3)?
thanks

Yes…and I am trying to remember what the guy called it (besides 9.3/338)

**Sorry - can't rememeber. Had an Alasakan name... I think the guy even had RCBS make dies. It was very close to a 9.3 x 64

OK, I'll be damned... it had an Alaskan name because 366 Alaskan WAS the name!

interesting
I was looking at the 9.3x62 and the 338 win mag cases and it looks like a cool wildcat.
thanks for the info
cheers

I have both and they are both great. I can get 2505 with a 286 North Fork from my 9.3 so I am quite happy with that.

I am not familiar with this cartridge, but I know the 9,3x64 Brenneke very well. The cartridge 366 Alaskan will be comparable to that in terms of performance. In any case, it will offer more than the cartridge 358 Norma Magnum, particularly regarding the bullets.

There was a guy on a forum out here who said he had invented a new cartridge by necking up a 300/or 338 win mag case to 9.3 and about three or four of us said it had already been done and a couple of people correctly named it, being someone of fragile ego he had a tantrum and complained about us to he forum owner that we were picking on him . Never heard anything more about it
I think the 9.3x64 would be a good contender for the job and without special dies etc

I have heard of people stuck for 9.3X64B cases using belted magnum cases, turning off the belt and reducing the rim diameter to make brass. Aneal and full length resize and you have 9.3X64B substitute brass made from 338WM or 300WM brass.
So ballistically you might as well get a 9.3X64B rifle and save some bother.
