That would depend..
Shooting strings of shots will get the barrel hot..
The odd shot it will probaly last forever...
My current 1 in 9 twist barrel has done I think 1630 shots and must be nearing the end of its life..
The worn barrel may have contributed to the ELDMs blowing up 🤔. Never had any hybrids not make the target..!!
I only shot 3 or 4 matches with them and the last 2 I had blank targets..
Dropping a point hurts... 5 points is total disaster..
If You checkout accurate shooter there's plenty of info on them blowing up, usually happens before 300yds....
