The "DuPont Lure" has been a tried and true redneck fishing technique, probably since not too long after Alfred Nobel invented Dynamite.

On the other hand, a frag adds a little something extra to the mix, not to mention the unpredictability of eastern block fusing, see below:

For bayonet fighting, the longer the better according to the reach theory that was popular prior to WW 1.

The pressure generated  inside the bore by firing a rifle does not decrease to the point of allowing the bullet to slow down before it exits the muzzle. The rate of acceleration may decrease if the barrel is long enough. Muzzle blast does not happen without built up pressure. There is much greater pressure behind the projectile than in front of it. Without this pressure there would not be the sound of the rifle being fired. wM1

Sorry, that has been proved wrong to many times to dispute.

Nothing to dispute. A 10" barrel in a  produces less velocity than a 20" barrel which produces less velocity than a 30" barrel with the same load; Hard to believe anyone would think the thousands of lbs of pressure generated buy a fired cartridge could disappear in the minute fraction of a second it takes a bullet to exit the barrel.  Think about it. Where does this pressure go? You hear the pressure being released when the bullet exits the barrel. wM1

For another thing, until the advent of smokeless powder, you got more velocity from a given charge of BP in the longer barrels...at least up to a point (of the bayonet???  ;) ).  Shorter barrels didn't "shoot as hard" as longer ones, as a lot of unburned or partially-burned powder was blown out the muzzle of shorter barrels.  Of course, long-barreled muskets were inconvenient to carry on horseback, unless slung over the rider's shoulder, which could get very tiresome in short order. Hence the introduction of the carbine, musketoon, etc. Cavalry figured to close with the enemy much more quickly than opposing infantry, so some decrease in range was allowable.

Uh, no.  That this OWT persists is due to BPs burn rate being unchanged when unconfined.  In fact BP burns very slowly when compared to Confined Smokeless, where the burn rate is accelerated exponential to pressure generated. BP is a mechanical mixture where the burn rate is controlled by the surface area of the powder grains.  And nothing else

 Thus longer barrels and still burning black powder grains being ejected from the muzzle.  The slower rate of gas generation is what limits muzzle velocity with BP.
Would seem to me if its still burning the bullet is not slowing down.
