30/06 argentine mauser

Da-Tank

have a modelo 1909 argentine mauser carbine that has been re-chambered by importers to fit the .30/06 case. I would like to know if I can reload .311 cal. bullets in the 06 case like the .35 whelen and other wildcats. Thanks

basicly yes you can, but first fire a standard .30/06 and then try a .311 bullet in the fired case. if it 'slips' in you are good to go (neck tolerences). most of the rechambered argie's I've fired shot rather well (min. of deer) with .308 bullets.

.311 (7.92) is not the same as .35 Whelen .358.

You must shoot only the cartridge specified on the barrel in that rifle. You can use .311 Diameter bullets in some loose chambers on a 30-06 or other 30 cal rifles using the proper expander ball while sizing. Loads should be reduced and signs of hard bolt closure will indicate you have a mismatch.

Bruce, his 09 Argy was originally chambered for the 7.65x53 Argentine round. A bunch of the imports were re-chambered to 30/06, making it a 31/06. Most are fairly accurate with 06, some aren't.
The 7.65 bullet was .313, so reloading an 06 that was fired in that chamber with a .311 or .312 bullet, improves the accuracy.
The only catch is, like Mike stated, the neck of the chamber is cut for .308, and if it's not loose enough, the .311-.312 bullets won't work.
Da-Tank, I would try 06 first, and see how it shoots. If the groups are too big, try cast bullets.

The one I had required .311 bullets for even moderate accuracy. Unfortunately, the chamber neck diameter was inadequate to accept normal 06 brass loaded with .311 bullets. I loaded some ammo using cases that had been neck turned sufficiently to fit.
I felt this was hazardous considering the possibility that this ammo might find it's way into a standard 30/06 so the 09 action was rebarrelled.
Mike Whiskey's suggestion is a suitable way to determine if the neck will accept and release a .311 bullet loaded in 30/06 brass. No other die is needed-the .311 bullet will usually fit. If not, find an expander for one of the .303/7.65/7.62x39 cartridges.

If the chamber neck is too tight to FREELY accept .31-06, you could theoretically have it reamed to suit.
Finding a reamer and getting it used at a reasonable cost relative to the value of the rifle might be a problem, though.

I think that says it best covering it both ways. The barrel, if original, will shoot .311"-.313 (.312" nominal) bullets. If the neck is only reamed out using a .30-06 reamer, there is a good chance it could be too tight and cause excessive pressures. I would not shoot a .312" or larger bullet in that until you got an idea of exactly how big the neck is.

That said, of the several I have owned only one was what I consider tight, and it was .003" over the finished neck size of my loaded 7.65-06. It was the most accurate.

I will note though that with cast boolits, you give up a world of velocity.[;)][}:)][:D]

I don't see where cast bullets would gain anything.
They would make it worse, if anything.
Say you have a .312" barrel. A .308" jacketed bullet MIGHT shoot ok, a .310" or .311" probably will. But you would need at least a .312" cast bullet and better .313". That would reduce neck clearance even more.

One option (since you reload) would be to neck turn the cases. You'd easily gain the 3/1000" difference required. Then either use a .311 expander ball or run the cases through a Lyman M die.

Did you slug the bore and come up with a nominal .311 diameter? Barrels range from .311 to .313 in the original cartridge. I would have no problem loading .311 bullets in the 06 case if the bore diameter is .311.
