I use word perfect save it in my docs, copy to a flash drive for back up and at the end of the year I print off everything for each rifle then keep the print outs in a binder
On the day that I reload I add all of the data, bullet ,powder, primer (with lot numbers) fl or neck sized and the seating depth, then store that in the aboved for the rifle.
On the day on the range ( or in the field ) what I add to my records is the date, load, bullet, vel, how many shots fired and weather. Also the groups and ranges and the ammo from witch loading session. Then on the bottom of the page is the rnds fired to date.
So I can open my binder (or wp program ) at any day and know how many rnds that rifle has shot, witch load produced what results, how many animals have been harvested by that rifle to date
