The code is long-since cracked on .270 Win...?

Having set my mind to loading for my .270 Winchester, I have run across what appears to be a standard load over and over again. That's 55.0 grains of IMR-4350 under a 130-grain spitzer (mine are Sierra Game Kings), good for a shade over 3,000 fps.

Parker Ackley's book says I can go to 57.0, but being as he's a raving lunatic I consider 55.0 a good upper limit. Besides which, 55 grains fills the case.

The consistency with which I encounter this load data is pretty striking; it's a "standard" load, like a 170-grainer over 30 grains of IMR-3031 in .30-30 is a standard load.

Based on my reading I expect this load to be both accurate, and strong medicine for whitetails. Is there any good reason to look any further?
