Had some trouble full length sizing by 6MMBR brass. Even after FL sizing the brass I could barely close the bolt. Had a friend machine a couple thous off my shell holder. Sized all my brass and all is well...so I think. Double check my shellholder and 8-9 thous has been machined off. Just sized 50 once fired lapua cases that are really hard to come by and expensive where I live. So my question is can I fire them back to size and keep using them with a new shellholder or do I chuck them?
