Remington and Winchester brass has taken a HUGE nose-dive in quality over the last 10-15 years.
I won't buy it any more, unless there is no other option.
Federal brass is difficult to find as a component. ...And the once-fired stuff often has the primer pockets blown from the factory load.
PPU is much more available now than even 2-3 years ago. It ranges from decent to good.
Hornady is decent.
Nosler is decent.
Norma is good.
Lapua is fantastic. (But you'll have to form .270 from .30-06 and end up with a slightly short neck.)
I won't touch PMC.
I avoid MagTech (CBC).
i was told that hdy brass is made in serbia i have some has funny letters on bottom. have no problems with it
What, exactly, is that cartridge? Is it even a brass case?
Steel cases are generally not considered reloadable, so I'm not even going to address that subject.
As far as reloadable, boxer-primed, brass cartridge cases....
Some companies (particularly Winchester-Olin) have a lot of contracts with European countries for metric cartridges: 7.7x58mm, 7.62x54R, 8x51R Lebel, etc. Sometimes, they add contracts for 'standard' cartridges.
However, the cartridge head stamps are almost
always clearly readable, printed in english, and nearly always labeled for the contract. ("Winchester", "S&W", etc.) They don't want you to know that you're getting import ammo, so they try to hide all evidence of the fact that it was made by (what is today) the lowest bidder.
The most commonly used foreign contractor is currently S&B (unfortunately). In the past, PPU was a favored contractor (much better than S&B).
I have never seen a PPU or S&B contract cartridge that didn't have the domestic company's name on the head stamp, with plain markings (not "funny letters").
The easiest way to (currently) get your hands on an example of this, is to buy something from the Winchester "Metrics" line of ammunition. It'll say Winchester everywhere, but they're crappy S&B cases loaded with crappy S&B quality control.

Domestic Hornady brass is manufactured in Grand Island, Nebraska, by "Hornady Custom Ammunition" (formerly "Frontier Cartridge" a division of "Frontier Ammunition"). ....Not in Serbia.
