Not really a reloading question, just a cartridge design question:

Why aren't there any straight walled rifle cartridges?

Obviously there are a lot of straight walled pistol cartridges that work well in rifles, even at high pressures (454 Casull up to 500 S&W).

So when Ackley and Weatherby were hot rodding rifle cartridges, why didn't they make them with true straight walls to gain more capacity? Why did they leave that .010" ish taper?

I realize the difference would be negligible, but I'm just curious as to the "why"...
