I annealed some 45-70 brass yesterday.
After annealing I sized and expanded the cases and went to load some.
Unfortunately, the first case had no case neck tension whatsoever. Boolits just spun in the case.
So I sized and expanded the case twice more, and it SEEMS that there is slightly more case neck tension now.
I did not expect this.
I'm I right to think that the cases may well be too soft in the neck at this point?
This is 45-70 by the way.
