By the way Jerry, welcome to the site. Thanks you guys. Next thing to do is find a good used scope for it.

Thanks Addicted. I'll save that sight. It's way outside of my purchasing power right now. I've got that little guy I'm shooting with and the little bugger needs something every week! Braxton sure is shooting well, though, and really digging archery.

Natchez Shooters Supplies has really good prices on scopes and also have "refurbished" ones. So after ya get a nice Nikon on there I guess I'd have to raise my offer to $200. You're gonna love that gun.

Thanks for the welcome. I have been a long time lurker
I have a nikon prostaf 3-9 on my 25.06 and I love it
Going to buy another one for my .280 good scope for the
Money. I have a bushnel banner 3-9 on it now not near as clear
As the nikon but it has been better than nothing.

The only thing I don't like about the 280 is the shoulder is a little different than the 30-06/270/25-06 so you have to fireform the shells. If you have a bolt gun I was told it can work, but it won't work in my Rem. 742, so I will just have to buy the brass.  Good thing my grandpa kept plenty of ammo around    so it will be a while before I NEED to get more brass.

I have never heard of that. I think with the semi-auto what you need to use when you reload is what they call a "small base" die. That may be hard to find for the 280 though. But I don't believe the 280 is any different than a 270 or 30-06 when it comes to reloading. If your 742 was in 270 or 30-06, you'd likely still need the small base die.

Negative.  The shoulder of the 280 sits farther forward/higher on the case than the 270/30-06.  Hold the rounds side by side and you'll see.  The deeper chamber kept the 270 shell I'd necked to 280 from being fully engaged by the bolt and prevented the firing pin from hitting the primer.  Both my 740 30-06 and 742 280 Rem shoot just fine using the Lee Deluxe dies, no need for the "small base" dies (unless those dies are considered small base?)
Either way, sorry to jack your thread OP

OK, I think I understand what you mean now. I didn't realize you were talking about making 280 brass out of 270 or 30-06 brass.

When it comes to ammunition and firearms, jarheads are sooooooo darn nit-picky, aren't they?.  Everything's gotta fit just right! Kidding aside, interesting stuff, iusmc2002. Thanks for adding to the thread. You too BC.

base to start of neck taper;   270=1.949;  280= 1.999;  30/06=1.948.  this is case measurement spec. not chamber spec.  You must have a tight chamber. Many times the chamber in a given gun from any manufacture will vary more than that from rifle to rifle in the same model.

are my calculations correct that the base to neck taper of the 7x64 is 2.16"?

[Bofire]

base to start of taper is 1.998   base to end of taper at base of neck is 2.198
Carl

this is for 7X64 Brenneke

Cool.

once again proving to be very VERY close to the 280.  I need to start collecting reloading books.
