Long story short:
I purchased a used 110BA LE in 300 Win Mag and the incorrect bolt was included.
Savage sent out the correct bolt for the rifle but my local shop doesn't have headspace guages for 300 Win Mag.
I removed the firing pin, ejector and extractor and chambered a factory Hornady round. Everything seems good...

Should I buy a set of go/no-go guages before i head to the range?
