Heres a great photo series that shows the innards on the 00 buckshot shell. You can see that white buffering material, and the shot cup that the buckshot rides in. That whole inner plastic cup flies down the barrel as an intact unit.
Thats why there can be no ricochets inside the barrel as that guy warned you.
As it clears the barrel, the plastic opens up like fins on a snake-eye bomb, and the shot is freed.
Oh, and that white granular stuff isn’t truly styrofoam, but it reminds me of it.
My guess about him thinking it can “rifle” the barrel was that he saw streaks of grime and lead fouling in a dirty barrel and decided it was rifled or etched by the slugs.
It was just dirty and a good cleaning will have it as good as new. Those plastic cups will leave a similar appearing fouling after a while.
Excellent, I really appreciate the information. I had never heard anything like this before as far as slug rifling a smoothbore, but I thought better safe than sorry.
But now I think I’ll get some slugs.
