NORMA 6.5 creedmore brass

Norma is the only brass I am using for creedmoor and never had any issues even with full power loads. Saying that there's always a chance of a bad batch or just few bad cases slipping thru QC
Its only ben 4 out of a hundred, problem is ive lost faith in it now , may have to get some new cases , i believe lapua are good
I can't comment on lapua as I am not huge fan of it. But personally I wouldn't be bothered starting a load work again with new brass( unless there is no choice) . Since it's only 4 out of 100 I'll throw them in the bin and carry on with the rest as normal. Don't get it wrong way, but there's always chance of error by reloader, could be the primers and many more reasons. All I am trying to say is 4 case failures are not enough to write off the rest
Interesting. Just for clarification, what do you mean by ‘blow out’ in this instance?
Have you changed brass manufacturers without adjusting the load?
on ejection primer was out of the brass
No they were hand loads on their 2nd cycle of reloading,
No mate its the same workup i've always used nothings changedHave you changed brass manufacturers without adjusting the load?
Thanks for the clarification.
So the pressure exceeded the elastic limit of the case head & the brass was pushed well into the plastic stage of deformation.
Either the head of the case was softer than normal or the case was fine but pressure was higher than you usually have (or an unfortunate combination of the two).
I’ve just stated the obvious of course but it basically comes down to nothing else - as for why it happened? It could be an odd case being softer than it should be (unlikely but possible) but are you sure there could be nothing that could have caused pressures to be either higher in just those few rounds or perhaps generally higher in all with a few rounds being higher still?
