I don't bother with a printed page, but use lined notebook paper. There are three major sections in the log:
1) Log of rounds reloaded, with the following columns: load identification (e.g., 45ACP-RR1), number of rounds loaded, date
2) Catalog of loads with the following columns: Load identifier (e.g., 45ACP-RR1), powder and charge weight, bullet, brass, primer, source of the load data (e.g., Speer 13). This is followed by a notes section with OAL, published velocity and my measured velocity, published max charge, if it's not good, then why is it no good, if precision accuracy at long range is necessary, then a sample five shot group, and any other info that is worth preserving about the load.
3) History of developing special loads, like a load that is both reliable and accurate in a target pistol. This usually takes a few tries, sometimes several tries. It is mostly notes on the problems encountered during load development and the result is a chronology of how I developed a good load. I have only used this section a few times.
Additionally, for high pressure bottleneck brass I always load a whole box at a time and tally how many times that box of brass has been loaded. I then discard the brass after it has been loaded four times.
