That is Holland's perspective on the paradox but not Westley's. Their guns were marketed to shoot further and hit harder. There is an abundance of material from "the day" to indicate this. The rifled choke gun is not a long range weapon. It is a gun of versatility and opportunity. Any advancement that increases the versatility increases the opportunity as well.

The proof will be in the pudding when the capped bullets or a reasonable facsimiles are available.
Just a couple of years ago the original velocities were unattainable at reasonable pressures. That has been overcome. I am sure that a capped like projectile is not far off.
