Klikitarick-I really don't see the problem here.It is proven and even documented the modern 45-70 can safely handle 40,000 CUP.If you choose not to go there,then don't.There are some who choose to do it and do it safely,so let's let them do it.There certainly is a margin of error built into it because the action has been tested way above 40,000 CUP without failure.The one's that failed were in the 70,000 category where know man want's to be.40,000 CUP is max.With a chronograph it can be reached easily without hitting the 50,000 you talk of frequently.Wild West guns has tested the action to 50,000 with know failure and yes there are some that load to the mid 40's even factory without a law suit yet.If your not comfy with it,so be it.But other's are and can get the most out of there gun without harming it or thereselves.
To each there own on this one.Good luck.Jayco.
