loading for an 03A3 .3006

Anyone load for this? My dad gave my son his sporterized 03A3 and he wants to hunt with it. I load for my '06 (51gr 4064,150 SST). Any suggestions? Thanks

Re: loading for an 03A3 .3006

Shuey: I'm no expert on O3A3's but if I recall you should check the serial number of your rifle. Prior to a certain serial number the metal used in the receivers were not as strong as later production rifles. Thus if you have a "low number" Springfield receiver your loads should be reduced somewhat from modern day '06 loads. I'm sure someone here knows better on this then I do, so hopefully they'll let you know for sure. Good luck.

Don't treat it like a new rifle. The U.S. had problems with heat treating the rifles at that time and that can cause problems when firing the rifle. I'd check the internet for that information. Somebody is out there that specializes.

Re: loading for an 03A3 .3006

This is my hunting load for my 1903A3. Its Hornady 150gr SP bullets over 47.0gr of IMR-4895 in Remington cases and CCI 200 primers.

This is a 5-shot group at 100yds using open sights from a rest. My '03A3 is a very accurate rifle!

Re: loading for an 03A3 .3006

Sorry to mislead. On second thought I knew the rifle was probably older. Here is one source I found saying it was not a WW One rifle. Here is one specialized site I found. Just enter the rifle "O3 A3" in your search on the internet.
And remember every rifle is different. Some can shoot; some can't or shouldn't be shot.

Post U.S military issued O3-A3
Hello there,

I wonder if anyone can help me?? I have just registered, and am excited to learn some information regarding a rifle that I just inherited. It is a U.S. military issued O3-A3. The serial number is 3499642. I am curious as to when it was manufactured. The rifle is in excellent condition!!! Any idea to what it's value is??

Any help would be greatly appreciated!!

Thanks,

The 1903A3 was approved for issue in May of 1942. Of basic Model 1903 design, it was modified to simplify and speed production by using stamped bands, swivels, butt-plates, and magazine-trigger guard assemblies. They also utilised a simplified front sight and an aperture rear sight, mounted on the rear receiver bridge. Remington began production of the rifles in December 1942, and continued to assemble them until sometime in mid-1944 (the contracts having been cancelled in February). Approximately 707,000 were produced by Remington. An additional 234,000 were produced between October 1942 and mid-1944 by the L. C. Smith-Corona Typewriter Co., and in 1956 Springfield Armory built 850 M1903A3 National Match rifles using pre-war bolts and milled trigger guards. The M1903A3 can be found with 2, 4, and 6 land-and-groove barrels.

According to the serial number chart accessable from this site's homepage (click on MANUFACTURE DATES; then 1903 AND 1903A3 SERIAL NUMBER TABLE), your rifle was probably produced in March 1943.

If still in its military configuration, I believe there should be a date stamped near the front sight (MM/YY).

Hope this helped,

Re: loading for an 03A3 .3006

800,000 was the cut off for the bad receivers.

Is your position a short term gain - or a long term loss? Separate the issues.

Re: loading for an 03A3 .3006

NO, repeat, NO 1903A3 rifles had any heat treat issues. They were made after that was rectified.

The 800,000 number is the cutoff for Springfield arsenal manufactured M1903 rifles. Rock Island Arsenal also made M1903's, and their cutoff is a different number. I think it's around 285,000, if memory serves. No 1903A3 needs to be considered unsafe be virtue of the heat treating it received.

The 1903A3 was also made by Remington and Smith-Corona, never made by Springfield or Rock Island, and the heat treatment issue, anecdotally, seems to be more prevalent in rifles made during or shortly before the US' entrance into WW1. Prior to that, experienced craftsmen could observe the color of the steel to know it was the proper temperature.

During ramped up war-time production, new employees didn't have the time to get that experience, plus it was reported that open windows made it that the weather (cloudy or sunny) influenced how the color of the steel was seen and mean the steel could be "overcooked" or "burned", making it brittle.

Interestingly, the USMC was short on funds for rifles as WWII came to the US, and the proofed and reissued "low number" M1903's with 80,000PSI proof loads. Those old rifles were retained and used in combat right up to and including Guadalcanal.

Again, this was ONLY in Springfield-made rifles under S/N 800,000 or Rock Island-made rifles under S/N 285,000 (roughly). NO 1903A3 rifles are affected by this.

I have shot Hornady light magnum ammo in my "high number" Rock Island M1903 with good results.

For handloading, I used a Hornady 150gr SP Interlock on top of 51.5gr of IMR4064 with good results on my 1903A3.

Re: loading for an 03A3 .3006

Just loaded Hornaday SP Interlock 180 gr with 54 gr H4350.

Otherwise my 03 loves Rem Core Locts in 150, 165, or 180.
