The good news, is that you can use the well known properties of 4130 / 4140 and 416 SS as your baseline, and compare the properties of "alloy xxx" to it.
It is common in metal alloys that when they improved one area (for example tensile strength) it might decrease fracture toughness or something else. This is the whole trick with base metals and alloys - it is all a balancing act.
A good example is steel barrels vs 416 SS barrels. The stainless barrels are dramatically more corrosion resistant, but the tensile strength is significantly less, as is thermal conductivity.
The more complex comparison is not just what happens at room temperature, but also over the expected use temperature. Some steel alloys become quite brittle under arctic conditions, while many aluminum alloys are used down into liquid N2 temperature ranges.
I wouldn't be at all afraid of building up a .22 LR setup with bronze, but moving up from there, it might be helpful to use a pressure trace or similar so you can monitor how much things are deforming (or not).
