After monkeying around trying to move my natural pattern location to the bulls-eye, I've come to the conclusion that hitting the dead center of the silhouette, and getting patterns you can cover with a .50 cent piece, is over-rated. I'm able to hit center mass with the .380, 9 and .44 single handed, at the closest and furthest distance the indoor range allows, with nary a miss... good enough for me. I have not seen that pie chart Josh, but it does seem to fit what some had suggested was cause for my low and right tendency. According to the folks at the local range, it's the most common problem for shooters of skill level. Let 2014 be a pivotal year for squashing gun control initiatives and re-affirming our 2nd Amendment Right!
