Hi all quite new to reloading so you will have to patient with me.
i have reloaded some factory round ppu brass and after one reload most of the cases have tiny splits around the top of the cases.
i have some Winchester brass and i have reloaded this 6 times and its fine.
the one thing i have noticed is that the factory ppu brass has some strange crimp type marks where the splits have appeared .
was going to attach photo but cant see to do it for some reason ?
please advise. wtfwtf

Re: .44 Magnum brass splitting !
Suggest that you anneal the brass.
Was the brass, both Winchester and PPU, bought second hand/new or fired factory by yourself?

If the brass is from new then you would be best placed to know the cause of any crimp marks.
Is all the brass trimmed to the same length?

Re: .44 Magnum brass splitting !
Looks like a very hard crimp guaranteed to work harden brass unless annealed.
Is it a Lee factory crimp die you are using?
If so it is a brutal tool and should be used sparingly.
What about case length?
Any reason why you don't shoot cast boolits?
They take a gentler roll crimp.

the case on the left is the result after the first reload of the factory round.

Re: .44 Magnum brass splitting !
Damn! I have cases split on me all the time now but that is because my brass has been reloaded an unknown number of times as it was secondhand when I got it.
As Dromia says, use a very light crimp. As long as it holds the boolit in place in a tube magazine and can stand the pressure during loading then that's really all you need.
What powder charge are you using?

It's not the pace of life that concerns me, it's the sudden stop at the end!

i think my crimp is light, the powder charge at the moment is 9.2 grains of unique 240 cast bulletMike357 wrote:Damn! I have cases split on me all the time now but that is because my brass has been reloaded an unknown number of times as it was secondhand when I got it.

tried all manor of variations from 6 grains up to 11.8 and this seems the most accurate.
