Anybody hand load their 308 Winchester barrels down to 45,000 MAP pressure?

I ask the question because have read that the SB2 frames like to operate at around 45,000 MAP pressure on cartridges that have a case diameter greater than .378 inch. I understand that Handi-Rifles have been chambered from the factory in a number of calibers with case size .473 thru .526 operating at up to the 500 Smith & Wesson of 60,000 MAP pressure.
I wonder if anyone has fired a couple thousand rounds of 500 Smith and Wesson thru a Handi-Rifle?
