Extractor groove is too narrow for most extractors to grip the shell on 30-06 and 270 cases.
Sometimes breaking the extractor..i have read.
308. and 243 and 7mm-08 all seem to have the wide extractor groove.
From the dead. Just an update the CCI 200 primers did not work really well every time.
I need to use softer cup primers in this.
I was reading the trimming 30 carbine thread and thought about how far I trimmed these .308 cases to make the 45 shot shells.
Then had to look up the thread.
I need to make some more of these.
