mathman,
That's eleven grains higher than what Hodgdon shows as a 53KCUP top load.
One of my strong points in life is ignorance. I use two criteria when accepting maximum loads. That is, does it work through the action like a factory load and do I get lots of reloads with the brass. With the loads listed I get at least half a dozen or more loadings per case.
But after reviewing the load in
red, there is a typo. It should read 90.0 grans for the 260 Nosler load. Thanks for catching it.
