Corrosive is the wrong word.

Errosive would be the correct word, due to higher flame temperatures.

However, that's pretty much a thing of the past due in large part to the aforementioned powder coatings, but also better steels.

Old British cordite was well known for its extremely high flame temperatures and its ability to eat the throats and rifling leads out of early Lee rifles.

In fact, the rifling change from the shallow Metford type to traditional deep cut rifling around 1895 was done specifically for that reason.

It's still not uncommon to find early, unrefurbished Lee-Enfield rifles with bad throats and washed rifling.
