Glad it intimidated the others into domestication

Also case in point that shotgun barrel length has little to no effect on projectile velocity, unlike rifle and pistol calibres.

Has a huge impact on spread and range though. And velocity does drop a bit with really short barrels (2-300fps) so less impact than rifle or pistols.

Most short Turkish shotguns have chokes- including this one- so no, it really doesn't. A much shorter sight radius doesn't help either, but that's why you use an optic.

Velocity doesn't drop as much as you think, either. Shotguns are basically just big pistols, and as such gain very little velocity after 12" or so of barrel (to the point where 18.5" and 30" get about the same from the cartridge). 18"-18.5" just sticks around because it's the US legal limit (and the Canadian one, when semi-auto), not because it's actually ideal.

.357 Magnum, .30 Carbine, and to a point .300 Blackout share the same performance to barrel length relationship- they start to really drop off once you go down to 6" or shorter, benefit up to about 12", with marginal gain after that.
