Well written post. Your argument is good news to me. I very much hope to emulate your "fat boy" (or "fat lady") with a fattie of my own. (If only the bloody shotgun would arrive !!)

"the trajectory never deviates more than ONE INCH from the line of sight out to 100 yards and slightly beyond"

Wow, especially as a .577 covers 60% of that difference anyway!

So you went for a velocity of about 1650 fps (650 grains) for recoil comfort reasons? Do you think a Greener Empire could take an 1850 fps regulation load?

Mate, I hope to catch up for a beer or two around plus or minus the beginning of August (hunting the first week of Auguist and also hunting another week either before or after that - not set yet). I would very much like to fondle your "fat lady" just to put "4seventy's" mind at rest that it will balance nicely.

Any chance of a shot? Maybe a "fat lady" is too much for me.
