Very well. Change bore axis to "axis of the bore". What I was saying is that if the bore of two different barrels were not absolutely concentric, it could be a possible mechanism for the slower projectile hitting higher.
You keep focusing on the sight heights on the different barrels and what I keep trying to get across is that the particular sights do not enter into the issue I am discussing. Forget about the fact that I have two different slides with different sights, because I can shoot 40 S&W and 357 SIG from both. I am not talking about a change in POI resulting from a change in sights.
The point is that in the P229 and P226 the exact same pistol (except for barrel) with the exact same sights will shoot the slower 40 S&W cartridge to a higher POI than the faster 357 SIG cartridge when using the same sight picture and shooting at the same intermediate range. Choose whatever sights you wish because they are the same for the two cartridges after just swapping the barrel. This has been observed by umpteen owners of these pistols who have changed from one cartridge to the other with only a barrel swap. I provided a few links to threads that discuss this. I could provide many more if I wanted to waste my time. I don't know how else to say this.
If as you say there is no change in barrel orientation during the internal ballistic phase, by what mechanism do you suggest that the same pistol with the same barrel orientation at ignition will shoot a slower projectile to a higher POI than a faster one?
