I was wondering if anyone knew of a necked up .338 case to .35/.358. If so what is is called and how does it perform. Thanks.

That would be awfully close to a 358 Norma. It performs as you would expect it to perform....... HTH, Dutch.

I used .338 brass in my .358 Norma quite a bit as I had a bunch laying around. Seemed to work great.
