probably a stupid question about shotgun barrels


New member
Would shooting shot out of a rifled barrel damage the barrel or change the spread pattern?

From what I've seen on The Box O' Truth - Ammo Penetration Testing , shooting shot out of a rifled barrel will have no adverse affects to either, as the shot is propelled inside the cup until after it exits the barrel. I'm no expert, but I believe this is the case with all shot. It never truly contacts the barrel.

I may stand corrected by someone that knows better.....

I am but a lowly internet surfer with some firearms experience. If I had a rifled barrel, I wouldn't have any issue shooting shot.

Happy research!
I know it's not exactly what you're looking for, but TBOT is a great site to look through. And from those two examples, I think you can extrapolate enough information to answer your question.

Actually if you go through the Box o truth testing it showed that the rifled barrel causes larger patterns with a "donut hole" due to the spinning of the shot and cup.

Let's try the Wolf at 5 yards with the rifled barrel.

Here's the results.

Notice that the pattern opened up to 18 inches, and definitely has the "donut" pattern as expected.
