Shotgun Porting - Mossberg

Sometimes I wonder about the usefullness of porting. I have a Mossberg with a 28" bbl and it is ported. I can't tell any difference from other guns I have with non-ported barrels. Watching people who have identical guns except for the porting shooting skeet and trap, I can't visually see any difference in recoil or muzzle rise. In the future I won't bother with it but I just had to have one gun with a ported barrel to find out for myself. Perhaps my shooting style isn't "refined" enough to tell the difference?

Well you could always just get a drillpress and some metal lube if you really need it on that 18" barrel of yours

My guess is that it's because the powder needs that bbl length completely burn.
I assume that is why a rifled bbl is (often) 20".
We'll see what other people say....

Tom Roster says that porting doesn't affect recoil, just muzzle jump. Jump is often felt as kick.
IMO, porting is better at separating folks from their money than their shotguns from kick.And, they're loud.

porting = panacea = psychological only, no real-world impact.
IMHO.
Take a cocktail napkin, inscribe the equations needed to calculate the amount of "thrust" needed to impact actual flip and/or recoil. Take the number so derived and speculate on whether the amount of, and speed of, the hot gases so required would easily eat through an upper barrel of an O/U shotgun with bottom ported.
If you're me, you'll decide the amount and velocity are insufficient to do anything other than crud-up the the upper barrel, hence adding interest to one's cleaning chores, and nothing else.
YMMV.

There are much better barrel alterations than porting. Longer forcing cone being the first to come to mind.
