7mm-06 - Anyone Have One?

[DuoGlide]

Have an interesting firearm built on a 1917 Eddystone action by one Fred D. Hays in Altadena, California who knows when. Gorgeous gun, beautifully blued, finished and stocked with a bedded action. Has a 26" medium taper barrel marked "Rock" slightly offset from the caliber marking.

Picked up a set of RCBS dies some years ago - they were a catalog stock item. Have only run 50 rounds through the gun and haven't been serious about load development, but that's coming. I put a file notch in the base of the sized cases so I don't get mixed up with my 30-06 brass.

Anyone still shoot these? I'm going to gear up to do some long range tests against my 7-08's and see if I can do cheap long-range shooting (cheap as in the rifles are bought and paid for a long time ago).

Would be interested in exchanging information on the performance of this round.

Ain’t that a 280?

And 7 mm Express.
Remington couldn't make their mind up on a name

Look for 280AI loads and start about 15% lower and see how that goes.
Should be able to find some sweet spot in there, just as any load development, work up cautiously till you find a load that works in your gun.
Is this a straight 7-06 with the 32* shoulder or an early version of the 280AI?
The first adapters of the round used the same shoulder angle, same body taper... Then along came PO Ackley.

Maybe not, the early 7-06's were exactly that, same shoulder and body taper...
Just necked down to 7mm/.284... Then along came PO Ackley = 280AI

Millions of people do, they're now called 280s lol

I’m gonna just speculate that 280 load data will be close. Which is what the question was.

Performance wise, yes. However, they're not identical as Remington moved the 280's shoulder forward by 20 or 30 thou' to stop 280s chambering in a 270 Win rifle.

Therefore, to convert 30-06 brass into 280, a false shoulder has to be created in the lower neck and the case then fireformed in the 280 chamber. If the OP also owns a 270 Win rifle, or it ends up in the hands of one such, they have to be very careful never to mix the two cartridges (7-06 + 270) up.

Look for 280AI loads and start about 15% lower and see how that goes.

Why 280AI? The 7mm-06 and 280 Rem case capacities are so close to that standard 280 Rem loads data is not only usable, but safer.

That's all it is. I've just been using 30-06 necked to 7mm. Guess reaming the chamber to an AI would be a project to keep in mind.....

The 7x64 Brenneke came to mind first when I thought of similar cartridges.
The 30-06 is the 63mm in length so I was thinking start with lower end charges for the 7x64 and/or 280 Remington. Although the 7x64 has a max of just over 61,000 PSI I don't think I would go there without knowing the Eddystone could hold it.

I have 2 7-06 AI's. The 7-06AI is shorter (between 0.030 to 0.060 shorter than the 280) than the 280 Rem. Mine were made before the advent of the 280 Rem.
