A poorly spraying nozzle did this.

--Exactly. I rest my case.

ANY nozzle this is malfunctioning will cause damage. A new nozzle (of whatever Pintle-type with good spray-pattern) will be fine....

Here in Europe, I have seen 220 types and the 1510 used in 'standard' swirl-chamber engines, and in MB Pre-Chamber types....
