I went to the range today and fired my Marlin 22 mag bolt action for the first time in ages.
I had Winchester x 40grn which I bought many years ago.
About 1 in 10 cases would not eject and used a cleaning rod to remove the stuck cases.
Every stuck case had split.
I have seen on the net many complaints about Winchester 22 WMR cases splitting.
Surely there can not be that many rifles with camber problems in the world.
I recall my son's 22lr having similar probs with Winchester brass.
Anyone experience this problem with Winchester 22 WMR cases
