The greater the gap between the forcing cone and cylinder face, the better chance for flame cutting.
I own an early model Premier grade Freedom Arms .454 Casull, with well over 1000 rounds thru it, almost all being full-power loads with tough bullets. Absolutely no sign of flame cutting or forcing cone erosion.

If you buy quality firearms in the first place, the odds of such damage is decreased, IMO.

I'd rather be a free man in my grave, than living as a puppet or a slave....
