Jhon, the damage to the bolt is minor and should not pose any issues. The rifle still shoot and groups well enough, keep shooting it and forget about the flame cutting on the bolt face.
The cutting should clean up nicely within 0.1 to 0.15mm - just moving your head space out of spec - If you've got the gauges you could set the barrel back a bit and thats it.
If it was me, I'd shoot it until the rainy season and then send it off for repairs - if I feel like it.
