Sorry this is so long but I can't post scans of the sheets and labels.
Here's my system for load testing. It might work for you, might not. First I always load in increments of 5 or 10 rounds and use a box that has rows arranged in patterns of 5 or 10. If I am testing a total of more than 20 rounds I will load up at least five fouling rounds using bullets with slight defects. The foulers will be used when I sight in or wipe between strings. The 50 and 100 round MTM boxes are excellent. I use Avery 2X4 mailing labels to identify the content of a box. They are printed up with the following text:
Date ______ Caliber _______ Load Series__________
Case_____ Primer______Powder______ Bullet______
Row 1_________ Row 2_______ Row 3_________
Row 4_________ Row 5 _______ Row 6 ________
Row 7_________ Row 8________ Row 9 ________
Row 10________ Notes: _____________________
I downloaded the reduced 1000 yard target available at http://www.bpcr.net/index-a.htm
and used Publisher (an older Mircosoft program) to create a data target that has the bull printed in the center of an 8 1/2 x 11 sheet of paper. At the bottom of the page I inserted a text box that has this information:
The last element of the system is a page called a bullsheet. At the top are four small target images created from the reduced target and modified in MS Paint to be very faint gray instead of black. Next to each one are number places to enter the velocity of five shots, the average, hi, lo, ES and SD. The bottom of the page has a textbox with this information:
Date _________________ Place _____________ Time _____________
Firearm _________________ Cal. _____________ Range ____________ Sight ______
Temp. ______ Humidity. ______ Wind _________
Case _________ Primer ________ Powder _______ Bullet _________ Wad ________
Load Notes ____________________________________________________________
Chrg. 1______ Chrg. 2 ______ Chrg. 3 ________ Chrg. 4. _________
In use the system works like this. I transfer the pertinent information from the ammunition box label to the bottom of each target and the bullsheet. Number them 1 thru 4 and put them up at 100 yds. I also post a fifth target labeled "S" for sighters and fouling shots. I fire a couple of the fouling rounds on this target to check setting and foul the bore. I then fire five shots on the target that corresponds to the test rounds, record each velocity, and mark the shots impact on the corresponding target image on the bullsheet. When the targets are pulled they are stapled or clipped to the bullsheet. At home groups can be measured and analysed. All elements can then be punched and placed in a ring binder or scanned and placed in a computer file. The entire system is made up of elements that are free (the target image) and entirely customised to any system of testing that you want to use. The bullsheet alows you to analyse the effects of velocity variation and see how a group developed. To identify the load serie I use a combination of the caliber and the date it was loaded, 457021406. I also keep a log book in a small bound memo with details of the load series and analysis that includes notes on what I feel should be tested in the next series.
You can't always win. You won't always lose. But you can always be a gentleman (or a lady).
