Question? I have an original U.S Military 1903 Springfield issued .30-06. Based on the serial number only how can I tell what year it was actually made? Also the gun has been fired thousands upon thousands of times. How does a person check for barrel wash? Can I assume that since it is an original .30-06 that it was made in 1906?

The gun has been sporterized new stock, bedded, floated, non military issued scope etc.. it shoots 5 shot groups of less than 1.5" at 100 yards.
