You've just stuck an exploratory toe into a very deep and turbulent pool. The strength of actions -- more specifically their receiver rings -- is not nearly as simple a matter as our druthers tell us it should be.
<br>
<br>For instance -- if I understand it correctly, the weakest of the three things working together to contain high chamber pressures (case, chamber, and receiver-bolt lock-up) is the receiver. It depends heavily on the head of the case to keep the rising gas pressure contained, and it goes to bits and pieces surprisingly easily if the case head gives way and lets wild gas get loose. I'm told (don't know whether it's true) that pressures as low as 10,000 lb/sq in. are enough to burst a receiver if the case lets wild gas loose to rampage through the action.
<br>
<br>I find this scary enough to make me VERY careful about keeping gas pressure well contained at levels well below "maximum," whatever that is or how it's determined.


"Good enough" isn't.

Always take your responsibilities seriously but never yourself.
