My point exaclty. Trying to remember stuff & transfering data can be very dangerous. Verify the data, write down, double check that, Then when you actually reload, double check that. You can never be careful enough. I read stories all the time of really stupid reloading accidents that are 100% preventable. Like a recent one of a guy loading PP instead of some stick powder into 223 rounds, KB is AR & his buddies in a 3 gun match. How, the powder look nothing alike?? Read the lable, verify everything 2, 3, 4 or as many times as needed to NOT make the mistake. Anything else is a Darwin project IMO. Harsh yes, but I may be standing next to you when your gun self destructs. I hate that.
