Well, I've gotten some interesting shooting technique comments posted directly on the YouTube comments section, not from anyone here. Both are good suggestions but I thought I would explain here why I can't adopt them.
"Your left hand grip is too weak"
"Don't cross your thumbs"
My left hand was severely injured years ago (non shooting related and non direct military) and I have little surface feeling and am missing a few nerves and muscles. I do the best that I can. I can't fold my thumb "correctly" forward and my strength is definitely low. I can and have shot left handed but I am just a wee bit handicapped compared to any typical run and gunner.
At 100 and 200 yards from a wrist rest, eyesight is a bigger factor than grip, and, with my single hand standing bullseye background I know exactly how much strength is needed to grip the gun to get an accurate shot. These guys probably meant well, but these are my excuses and I need to rely on my excuses sometimes! Weak and improper grip will never be on my excuse list for a poor result shooting long distances at a slow fire pace.
Rant off. Don't put me on a timer. Been there, done that.
