Does anyone know if it will be worth it for me to upgrade my target hangers from 5 grade carriage bolts to say grade 8 hex head bolts. This is was happened with in about 4 shots of a 308 at 100 yards. The carriage bolt had been running through the target but now is missing the head.
I don't trust the grade markings on cheap import bolts, I suspect that a Fastenal or Wurth labeled "Grade 5" would hold up better than a cheap bolt marked as Grade8.
