I reload my own ammo and occasionally a few rounds for friends. I have log files for each caliber and I recently wondered how many rounds I have reloaded for the various calibers. The log files were simple text files and included calibers for which I just did some chronograph measurements and calibers I only did preliminary things like explore powders and bullets to use.
It turned out that the typical log file entries were consistent enough that I could write a simple program to count the number of rounds I reloaded. A typical entry looks like this:
12/27/2014 100 rounds. Win primers. 180 grain Winchester JHP over 6.0 grains of N350. 0 rejects.
All the program had to do was search each line in the files for the word “rounds” preceded by a number then sum those numbers. I found a few cases were I had recorded group sizes or chronograph tests that match the format and changed those to something like “10 shots over the chronograph” from “10 rounds…” and ran the program on *.log in the reloading directory. The result was about double of what I expected in every caliber:
223.LOG: 2027 rounds.
22LR.log: 0 rounds.
3006.LOG: 467 rounds.
300WIN.LOG: 1351 rounds.
40SW.LOG: 34941 rounds.
45.log: 0 rounds.
9MM.LOG: 18643 rounds.
Total: 57429 rounds.
It’s not near as many as a lot of people but I was still amazed. Of course I did start reloading on October 3rd, 1996 which is over 18 years ago. So that only figures out to about 3200 rounds per year. I’m hoping to up that considerably and do a lot more shooting this year.
