Do you shoot “Report Cards”?
A friend dropped by to do some target practice and caught me shooting Report Cards. I’m still not sure if he thought they were COOL or NERDY. LOL!
OK, For transparency, I’ll admit that I’m the kinda guy who reads the instructions BEFORE assembling/using something and I have a habit of downloading Users Manuals before purchasing a produce. …Maybe I shouldn’t have admitted that in public.
In my defense, I worked in high-tech for 50 years and taking detailed notes about process, procedures, and product design/development was always a good CYA (Cover Your A$$) idea.
As far as the Report Cards, I use them to keep track of how well the airgun, ammo and shooter (mostly the shooter) are doing. I shoot five groups of 5 and 25 single targets (a 5x5 array) to give me 50 shots on one target face to evaluate.
The groups are measured in the conventional way (Center To Center); the group sizes are added and averaged to give me a number for reference that I call AG (Average Group).
I measure the single targets from the POA (Point Of Aim) center to of the POI (Point Of Impact), total up the row values and average them. Then I average all the rows to give me a number (AR – Average Radius) that represents the distance that I’m “off the mark”. Just for giggles, I’ll double the radius for the AD (Average Diameter) number that, theoretically, should be similar to my Average Group size.
Shooting a Card gives me a decent sample size (50 shots) and presents all of the impacts on one target face so that I can see what is happening. Is the airgun shooting consistently? Are there lots of fliers? How is my trigger control, focus and follow through? Am I canting the rifle (again)?
The Card gives me a good idea of the performance I can get from that airgun, at that distance with those pellets.
NERD WARNING – In addition to saved pictures, I track the report cards in a spreadsheet and can relate the performance back to tuning notes and velocity graphs from my LabRadar.
I don’t need much excuse to shoot but it’s always good to see if one is improving or back-sliding eh?
So, do you have any formal or semiformal way of tracking your shooting performance?
Cheers!
Note: "X" is a null shot (from cold fingers) and not counted.
25 yard target
40 yard target
