4 external factors
I usually need more than 4 external factors to explain my bad shooting.
Like
10mph wind from nine o'clock (at an indoor range)
Guy next to me fired a .45 Laudenboomerkarabiner just as I was squeezing the trigger
Danged bird crossed my sights just before the shot was let off
Had too much coffee that morning
Guy next to me shot my target with the same caliber
I used different ammo from the ones the gun was sighted for
Humidity warped the stock (not to be used with poly-stocked arms.)
Volume on my earmuffs set too high
I called that one (For all ten shots. Or five. Or whatever.)
Slide bit me. (Bring a red magic marker for the web of your hand for this one, just in case. Oh, and a band-aid.)
Oh, I was just plinkin', gettin' familiar with the arm
Volume on my earmuffs set too low
Did you feel that earthquake?
.... and many more, developed over the years....
Yeah, I know what you meant. Just kiddin'
I put one together like you're talking about using MS-paint a while ago, but the file got lost in transferring to another computer. I may have it on a CD somewhere.
