Thanks Bob.

My main point, bigger isn't automatically better, or more of these mammoth, overbore rounds would have caught on, which they haven't.

Efficiency, at least to me, is a big deal. Diminishing returns are just that, diminishing returns... smile

Balance is a big deal, at least for me.

I think the 26 Nosler is on the edge and for sure the new 6.5/300 Wby. I find myself working more with my 6.5-284 and 6.5 Creedmoor. I still like the 26, just have other projects ongoing that do what I need them to do. I don't have to burn 90 gr. of powder every time I shoot something... grin

My 6.5 stories are off the 7 mm topic, used as examples of what I'm seeing.
