I built a 338 Spectre SBR and ordered some of this 10mm mag to form for it. I have several firings with my brass and it continues to perform well. Thanks Starline for making this good stuff!

This is THE brass to use if shooting the Teppo Jutsu .338 Spectre. A quick trip through the sizing die and you are done. I have cases with 11 loads on them and they are still going strong.
