This is what it looks like now
Before I TIG welded it, it would bulge a case at ~25% extra powder.
Since I re cut the chamber and feed ramp with support to the case web, I have overloaded it with 180 gr bullets and Power pistol with 68% overload, and it could go higher. I have overloaded it today with 200 gr bullets and 800X powder with 106% extra powder, and I will go higher.
