What this does: When you fire the round.the brass will expand to fill the chamber.if you neck size only.then the case body remains matched to your rifle and your reloaded ammo is UNIQUE to your rifle.but all loading data and technique will be as any 30-06 round a bit of a widcat round made just for you. After all your cases have been fired once.I would then neck size the brass.You can purchase a dedicated collet die from Lee Precision to do this. If you go to the Hodgdon website, you can access data.I would suggest a cast lead bullet in the 150 to 175 grain weight class.in GI brass at the Trail Boss suggested starting load.
If it checks out.I would then suggest that you shoot it with reloads.Check out a powder by IMR called Trail Boss.this is a smokeless powder designed to be used in older produces much lower operating pressures. What I suggest is that you have the gun checked by a military savvy gunsmith.

take note that is you reload.most every loading manual has a warning on GI brass and instructions to reduce.even the suggested starting 10% The heavier brass will help deal with the GI guns headspace and oversized chamber. like the 30-06 loaded for the military uses a heavier walled case.outside dimensions are the same as commercial, but because of the heavier sidewalls and and casehead.they hold less powder. GO.No-Go and Field.Ideally a bolt drops on the go gauge but noe on a No-Go and NEVER on a field firearms are put together so that they drop on the No-Go and not on the field.The reason being that the rifle must function in the field when in combat and slop is everywhere and cleaning is an issue A tight headspaced rifle is accurate and super on the will get you killed in battle. I suspect that the "blow-ups" come from Kitchen table gunsmiths that think all you have to do is screw a barrel in.throw a bolt togeter and slip it into the action.they think if it fits and is safe THIS IS NOT TRUE There are several dimension that must be tightly held.not the least of which is headspace.Add in the fact that some early bolt bodies were not properly heat treated(like certain early GI actions) pair one of those up with sloppy headspace and major fractures loom.As a rule of thumb.Headspace gauges come in 3 lengths. I have encountered many such om the Mausers to the springfields and the quality and safety is PER INDIVIDUAL firearm That said.I have seen reports that the NO recieavers are "cast" steel.That would be true.if you are not thinking that they are cast iron.My guess would be that these are INVESTMENT CAST a process used widely in the firearms field(think Ruger) and the process produces safe firearms as long as all tolerences are held. 1903/1903A3 parts are plentiful and fairly cheap.What NO did was produce their own recievers and then match them up with GI parts to get complete guns.The safety of such a throw together depends entirely of the people putting the guns together. It is(was?) and aftermarket assembler of the GI rifle. National Ordanance is NOT a military vendor. If you have ever written a piece about this I would appreciate it if you could email it to me. MY QUESTION.Are NO 1903a3 guns safe to shoot? I would have my gun checked for head space and if the head space is ok.would fire it with commercial and mil surplus ammo. locked.The gas came out of the space between the bolt face and the cartridge head and blew out the magazine well.breaking the wood. I have read many gun blogs where the writers say that NO receivers are cast and they have "blown up".The few pictures of " blown up" guns are actually rifles that have had a cartridge loose its head due to excessive head space. Now, I am semi retired and would like to shoot the 1903a3 for informal target practice.

I also cut off the end of the stock and made the barrel free floating. Mine came with a black plastic hand guard which I removed.
It has a Remington barrel on it ( 2 groove).Īll the parts appear to be what a Springfield 1903a3 should have.
When I got it I discovered it was made by National Ordnance. I thought it was a Remington make or Springfield mfger. Back in the 1970s I bought a 1903a3 rifle.
