Shooting steel through full choke/fixed full choke older guns

I did it in an old remington 1100 with a fixed full choke barrel...the damage to the barrel was not apparent, but it did shoot the choke out of it over a couple of years...basically, the pattern kept getting wider and wider and that was the reason...

I just had a modern screw-in choke installed and all was good after that...

ETA: I probably wouldn't shoot steel through a really old gun (i.e. a belgium browning) for fear of rupturing the barrel, etc...

I have never heard of a slug damaging a shotgun barrel...I think the wads are plastic in a slug and protect the barrel and the slug...

you have me curious now, though...

from wikipedia (so it has to be true)....

quote:

---

A modern shotgun slug is a heavy lead or copper-covered lead projectile, with or without a plastic tip, that may have what appears to be rifling, but these are special cuts in the slug to let it deform when passing through a tight choke.

My understanding was that the fixed full choke may be an issue only due to a longer than normal taper for the choke. Since an interchangeable choke tapers over 3 inches or so vs the 26+ inches of barrel.

also since modern shot shells have thick plastic wads that encase the entire shot load, the bore is protected from any steel on steel damage and only the constriction at the choke is of concern.


So then I have to ask what shot will compress and what shot will not. Supposedly #4 or smaller has enough room to compress where as larger may or may not, but who knows.


I guess ultimately patterning my gun is the thing to do and not shoot full choke.
