This post is about an issue I had with m 300BO pistol running today for the first time.
For the most part, everything looked good with ejection at 3 to 4 O'clock, bolt locking back and no pressure signs on brass. However, I was having failures to eject periodically where the ejected case stayed in the receiver and a new round tried to chamber under it.
This is my first 300BO PISTOL build but I have built several rifle versions. I used a H2 buffer and standard spring as per various suggestions I received. The BCG I used is a M16 type and I just used it in my 16 inch .223 and it worked perfectly.
I did notice that a couple of cases had extractor marks as if the extractor pulled over the rim. I use the spring with black rubber in the middle on all my extractors and haven't had a problem with them. Can it be that I need a H3 buffer or adjustable gas block?
TIA
