What is the 'safe to shoot' number for SA 1903's?
I have a SA 1903 dated barrel 1918 with serial number 832xxx. What is the serial that 1903's got the double heat treatment?

I have read that 800,000+ was within the safe range....

800k for SA

286k range for RI

800K is the accepted standard for Springfield double heat treat, although it is known that a small number of non-double heat treat receivers that were still in the production queue made it into the stream. I've seen some sources say 810K and below to weed out those few. For Rock Island, anything past 285,507 is "safe".

I believe that the CMP will not allow any SA 1903 under 810000 to compete in matches. So they sold 800-810 as high numbers but don't really consider them as such? Feel free to correct me if I'm wrong.

You are correct. While 800K is the standard cutoff, someone at CMP who was obviously deeply concerned for our safety, raised the SA nmber to 810K. Of course, I have one ... Good Shooting. ..

Best reference is probably the CMP.

CMP Games Rulebook (2018)
4.2.3 As-Issued M1903 Springfield includes:

Permitted rifles are the Caliber .30 U. S. Model 1903 and Model 1903 A3 Springfield rifles, except that Caliber .30 U. S. Model 1903 Springfield rifles manufactured by Springfield Armory with serial numbers of 810,000 or lower or by Rock Island Arsenal with serial numbers of 285,506 or lower may not be used in any CMP-sanctioned competition.

If I recall the 810,000 rule was an insurance policy decision. John Beard really does need to get busy on his book. It will be interesting stuff, indeed.

I was told that the actions were not heat treated in numeric order of production. They were done in large batches as they trickled in from work stations. As soon as there was enough to fill a batch they went in. This is why the cutoff is 810,000, from research there was significant reason to believe that "some" of the actions between 800,000 and 810,000 were treated in an earlier batch. So, the rule was made for 810,000 because they knew for certain that all actions from that s/n up were definitely treated under the new process. I guess this would make sense when you have countless work stations doing the same process, some actions are bound to make it through processes and checks faster than others.
Sorry guys but Springfield never did provide a definitive answer like Rock Island.
