get you some Rite-in-the-Rain paper and tape it to your buttstock. I hear you about the notebook, that is why my info is written and/or stored in a few different locations...including the computer.
There is no problem with having a different zero for multiple loads of the same caliber, just remember the dope for each or have it on you for quick refrence. you'll be good to go.
