Going with known performing loads, as with Nosler's data, saves a lot of random firing to establish a good combo.

It's an overbore round, but as someone said, it's not really overbore if you can find slow enough powder... grin

So, the slowest of the slow seem optimal in this application.

With these rounds, the 6.5/300 Wby included, you're buring a LOT more powder for a little more speed, diminishing returns for sure.

But, at long range, bucking wind, they're in a class of their own.

I like mine.
