I purchased about 300pcs of brass a couple years back and have had nearly 40% failure rate.
In a attempt to rectify I tried annealing all the remaining New brass after running it thru sizing die and still have a high failure rate.
I have tried different amounts & brands of powder but it seems to make little difference. It splits in as many as 4 places around the neck & shoulder area.
Did they have a batch of brass with issues?? Anyone else run into this? I have reloaded once fired factory 22tcm brass multiple times before some start to split, but this batch of new brass seems to be the issue.
