INFO on 7mm 06

The Big Mac
Subject: Info on 7mm 06
Goodmorning. I am requesting any and all information on reloding for a friend who has a rifle and cannot locate ammunition for it... Markings on the receiver are: 7mm-06-and 7X64 I am aware of the 7mm'08, but this 7mm'06 is somewhat new to me. (been reloading 30+ yrs.) From what I came up with is; Take a .30-06 brass, size to .270 and expand the mouth to .284. After reading several reloading books, I fireformed one of these pieces of brass and found
measurements to be VERY close to what I'm looking for at the shoulder and neck. Another reloader stated that to shoot only 7X64s due to it being originally chambered for that. The 7mm 06 was added so it could be sold to Americans and the rounds being really close in specs. I'm told 7X64 ammo is available. Please shed some light on this for me. Greatly appreciated.

    sounds like a 280 remington. 7mm bullet in a 30 06 case.

    Everyone has a photographic memory. Only some have film.

    When Remington introduced the 280 Remington Cartridge in the late 1950's, it was based on a "WildCat" cartridge called the 7mm/06 which had been developed years previously.

    The 7mm/06 was just the 30-06 necked down to accept a 7mm projectile.

    The 7 x 64mm Cartridge was developed in Germany after the First World War. Althought it's ballistically similar to the 7mm/06, the external dimensions are slightly smaller. This would enable you to fire the 7 x 64mm in a rifle chambered for the 7mm/06, although the cartridge case would be subjected to substantial expansion.

    My WAG is that your friends rifle was orginally built in Europe, probably for a G I or American civilian working over there. This would probably be before Remington introduced the 280, and the 7mm/06 was still a Wildcat.

    My 2 cents would be to take it to a COMPETENT Gunsmith and have him make a chamber cast to find out which cartridge the rifle is actually chambered for, i.e. 7mm/06, 7x64mm or 280 Remington. Once you find this out you can proceed accordingly.

    The 7mm-06 was a wildcat round that was somewhat popular in the U.S. before the advent of the 280 Remington round as a commercial factory caliber around 1957.It was also known as the 7mm Express Remington in the 1980s.-- The 280 is based on the 30.06 case also, but has had the shoulder moved slightly forward to prevent chambering a 280 in a 270 chambered rifle. -- 280 brass cannot be readily formed from 30.06 brass by simply resizing and necking down .06 brass in a 280 die because it leaves a minuscule shoulder that won't always safely control head space and can be prone to case separations. They form the 280 on different mandrels at the brass factories. -- The 7mm-06 is similar to a European cartridge that is known as the 7x64 Brenneke that used to be popular over there.I don't know if brass for it is still readily availible, but years ago I think was availible from Norma.-- You could probably have your chamber opened up with a reamer to make it a 280 Remington and utilize factory brass and pick up a little case capacity. Keep in mind that as with all wildcats the chambers can vary slightly depending on the reamer that was used and probably won't be uniform with other 7mm-06s. If you want to be certain of dimensions have a gunsmith make a chamber cast and measure it to see exactly what it is..............Good Luck.....[8D]
