Check out the current thread (above) on the PLY rifles. These make a total of 19 that we have been able to find and, obviously, more out there.

As to your lugs, if I remember rightly, Ross bolts were factory-lapped into the receivers as they were built. BUT if a bolt were worn unevenly on one side (as from functioning with mud in it for too ling between cleanings, a tiny amount of slop could conceivably appear. THEN you harden the poor thing glass-hard and start firing full-house loads... and the lugs shatter.

There are spare bolt-heads out there. Inspect your action carefully, get a spare head, lap it carefully into the action, check it out and go shooting. Be sure to have fun, too.

There are very few things more fun on a rifle range than a sweet-shooting Ross. That trigger alone is worth a book!
