And now to sum up. Hey, how do you sum up the replies? In just five replies, most brands are junk, or great, depending on who said it.
Even the good old CIL Dominion has been called the worst out there! Jack O'Connor, the undisputed dean of the US gun editors and writers, once advised hunters going into the mountains of western Canada to hunt, to wait and buy their ammunition in Canada, because the Dominion brand was so good!
The way I look at it is all the common brands have often been maligned, each it its turn, by modern shooters. However, each of those brands have been manufactured for a hundred years, or more. Does anyone think any brand would still be around and still actively used, if it was inferior? No way.
Most complaints about brass are caused by the reloader and/or his rifle.
A common complaint is primer pockets enlarging. Every brand of brass is designed to handle the pressure the rifle and case is designed for, without enlarging the primer pockets with only one, or only a very few loadings.
I cut my teeth on Norma brass and my sole loading information book was the 25 page, Norma Gunbug's Guide.
In that book Norma stated they receive complaints from reloaders about their brass being too soft and the primer pockets opening up with only one shot. Norma stated that lab tests constantly proved that it took in the order of 90,000 pounds of pressure to enlarge the primer pocket with one shot!
I personally have used every brand of brass going, and I have no brand that I will stay away from. The biggest difference in brass is in the weight variation from brand to brand. Therefore, one has to alter the charge of powder, depending on the weight of the cases. Remington is often the heaviest, while W-W sems to be about the lightest. But when loaded to the proper pressure I can see no difference in their longevity.
Another "fault" we hear on here about brass, is it "being so soft it almost has head seperation." That bright, shiny ring that shows up just ahead of the web on a case, sometimes being either and insipient, or full blown crack, is cause by too much headspace in the rifle. It is not caused by weak, or inferior brass.
