I created an Excel spreadsheet.
First I figgure out what I want to do a ladder test on.
Then I map out my 'range day' by listing all of my loads to be tested, with room to add velocity notes (and ES & SD) then group size and shape.
After I am done shooting I input all of the data I recorded into the spread sheet.
I then take a pic of the targets I shot with the notes I made on them (group size, load & other pertanent data) and put it into a folder with the ladder test I just shot.
Usually I wind up doing 3 tests with a particular Bullet & Powder combo if the 1st test shows some promise.
Example; In my 'reloading' folder I have a '30-06' folder, a '185gr Berger VLD' folder, a 'IMR 4350', a 'Test 1', a 'Test 2' and a Test 3' folder. Inside all of my 'test' folders there is a spread sheet and a pic of the targets I shot to fill in the spread sheet.
I then have a file in 'reloading' that has all of my 'loads' listed. So all I have to do is write down on hte cover of the MTM case the particular load that is in the box.
Don't get me wrong I still keep all of my old targets, I must have 7 or 8 file boxed full of them, but now I don't have to go digging through all of those boxes to find the one test I want......
Cheers!
