Yes, that totally makes sense. There's definitely a balancing act between barrel length, inside diameter, and compression. Captain Slug has been busy fine tuning these in his Caliburn blaster.

Ported barrels were just being introduced by Slug way back then. Turns out, like their real-steel counterparts, they do actually work. He released a couple ported barrel attachments for the Caliburn that further improve consistency.

But ... the data also shows that at typical velocities of stock and super-stock blasters, it doesn't make much difference. Apparently, it isn't until you get above 200 or 300 FPS that any of this has a significant impact.

So, I'm willing to qualify my previous advice to smooth the exit end of blowguns. Do it anyway, even though it probably won't make any difference 😉
