So what does that mean, we hold the .44Mag to SAAMI standard pressures but the .45 can be loaded to just whatever we want? What's the point in comparing loads appropriate to a $4000 custom five-shot to a $500 factory .44Mag? Why compare loads with a 50% safety margin to those with 100%? No point in comparing apples to mangoes. 99% of these discussions are comparing standard pressure .44Mag to "Ruger only" .45Colt. So the fact that 36,000psi .45 loads exceed 36,000psi .44 loads is irrelevant. There's no voodoo here, the data doesn't lie. If you compare maximum loads in both cartridges with comparable bullets, the result is that the .44Mag maintains a velocity advantage across all bullet weights. At the very least they're the same. Change a variable for one cartridge it's only valid if you change it for both. Seems to me that some folks made up their mind a long time ago and won't be swayed by the facts.
