Can a 7x64 chamber be re-reamed (cleaned out) to .280 Remington?

I *will* work but you're likely to have a very distinctive ring around the shoulder. It's best to set the barrel back a turn and then rechamber.

why?
brass? reloading? like 280 is easy to find.. they are they same round, just a slight shoulder/angle difference.

If you have a 7x64 keep it that way!!!!!!!!

It for sure beats the 280 ...

Look for RWS, Hirtenberg or Sellier and Bellot ammo ( which is cheapest, very accurate, take your pick about the bullets offered ).

Because of the long throat any European ammo will beat US made 280 or 7x64 ammo.

Actually I bought 21 boxes of ammo on closeout ($8.00/box) , so I guess I should not complain. I also have a .280. The Remington ammo is not very consistant, but I can live with it until I get some dies and reload. I have 12 boxes of 175 grain and the rest is 140 grain. The .280 lookes a little bigger than the 7x64, but around the shoulder it looks a lot different. I have been told you can reform .280 brass but I am not sure. I also have three boxes of Federal ammo, but they stopped making it. However I think enough is in the pipeline for a year or two. If everyone goes out and buys a new CZ 7x64 then they will make it again

Actually I am never satisfied fully with any rifle but that is my nature.

Remington sells 7x64 brass...I have a hundred new cases give or take 6.... I'd sell for how about $35.00 plus postage.
