This is the reamer I spoke of in my first post and the reamer I plan to order. I dummied up cases with a 215, 180 nab and a 165 partition to the same ogive to base length as the 215 at 3.740" coal. I wanted to see if it would work with "traditional" bullets. It will. It will also work with a 212 eldx. It will be hard to beat in the win mag and still be flexible. Thanks Broz for saving the rest of us reinventing the wheel. I look forward to your 30 nosler tests. For me it will have to be next time if it works out to be a real world advantage. This one will be a 300 win mag.
