I like really light loads in light guns, same reason as you.

Ted, All of the US (and European) cartridges that I have with the CIP mark are 2 3/4" and intended for 2 3/4" chambered guns so I will not shoot them in my 2 1/2" inch guns. CIP 2 1/2" (65mm & 67mm) cartridges are are proofed specifically for 2 1/2"chambered guns.

All of my guns are relatively light and light loads are much more pleasant to shoot.
