While many loads are tested in real guns, some are tested with a test barrel, which is just a barrel bolted to a block of steel, which is bolted or clamped to a bench. The pressure barrel will have a pressure measuring device, such as a copper crusher, to determine actual pressure of the load.

A pressure barrel will not simulate your gun in any way, so you should do as always, back off 10% and decide what do do from that.
