Stick,

<br>It depends on the diameter of the case. I'm of the opinion that it is a matter of time before we start hearing about more and more rifle failures, as they larger dia cases, ie 404 based and larger are becoming commonly available to the average hand"over"loading nimrods.
<br>
<br>As brass dia increases, the chamber is thinner, and the stresses are higher at the same pressure as a smaller case, and the backthrust on the bolt increases. We are still using the same actions designed for the -06 and 375 case head rounds, but now folks are pushing them harder with the larger cases.
