Just reloaded 36 cases for my NM Blackhawk .357, a new revolver. I used new Starline Brass and checked to make sure they fit in the chambers. I should have checked after loading the first one because they are a tight fit. My chambers will let a .357 Plus gauge pass through but two of them require me to push it through, it will not fall through. A .358 Plus gauge will not pass through.
The case bodies measure .377 in diameter, and fit in my GP100 chambers fine. However, the unloaded new Starline cases measure only .375 in diameter.
In the Blackhawk they require the ejector rod and a bit of pressure to remove them. Two questions.
1. What did I do wrong to cause the body diameter to expand that much?
2. Will the tight fit in the chambers cause dangerous pressure if I fire them? I am sure if I fire them the empty cases will be hard to eject but that is something I can live with. But I don't want to mess around with any dangerous pressure.
