I just got my Classic Arms PU a week ago - have not brought it to the range yet.
In my cleaning and pre-checks I was trying to cycle a spent case and the bolt was hard to close - then failed to extract. I had to use the cleaning rod - an extention - and a hammer to get it out (Was not happy). At first I thought it was the bolt/extractor... so I tried a bolt out of my seasoned mosin - same result.
So I thought - could be the round - I then tried cycling the round through my seasoned mosin and it worked - I used both bolts (PU and my seasoned mosin)
My conclusion is that it is the headspace that is just too much to hook the round to the extractor.
I have seen multiple posts about the what causes the extraction issues - and headspace is usually listed - but I have not found any the tell how to adjust it.
HELP ME PLEASE - I don't want my new Classic Arms PU to be a wall hanger!!!!
