Split case

[cjm1066]

7x57 Remington brass, I always check for split necks when reloading, as I clean, resize and trim to length.

Imagine my surprise on seating a bullet, neck tension suddenly went. Never happened before.

Try annealing, your is work hardened probably.

How many reloads have they done?

PPU is just as good in my opinion and cheaper!

Not a fan of Remington brass I have seen way too many smashed necks and body dents fresh from shipping.

That batch will get retired. Its 25 years old, very occasional tiny split on neck when when fired.

Is that all, Sheesh, they don't make them like they use to...

 

[303British]

25 years!

Surprised you have not had case head separation.

PPU reloads well, have a look at annealing, it resizes much better.

Don't forget to let us know how the next batch fares in 2051.

 

[cjm1066]

Why would I get head separation, it resized to minimise case stretch. The neck is what gets worked.

I have some Federal to use next, if I am shooting in 2051 I will update you.

Each time you fire the brass is steadily pushed forward, that is what you are trimming off, ultimately the walls of the case will become thinner.

But as you only trimmed them for 25 years they may be OK.
