How fast can a 300 win mag push a 230 Berger

[geo4061]

I barely broke 3000 with my ultra, 230's, and H1000. Flattened primers and stiff bolt. They did shoot a single hole at 100. Loaded at the lands. I dropped back one node. Accuracy is still there. It shoots three in a single hole. So, I really doubt this is possible with a Win Mag.

I had problems getting my RUM to those speeds with Retumbo. Wasn't really trying though. I ran into pressure just shy of 3K and it was enough to make me search for a lower node. My previous RUM sender was same story. I was close to 3K but one hot afternoon I had substantial bolt lift issues so I dropped to the node below. I too call BS. I agree stand WAAAAYYYYY back.
