Shooting off bags is not magic. You still have to do your part. It's still possible to have a bad day off bags. And it takes some experience to get good at shooting off bags and not everyone knows how to do it right (which is why I asked if you had done it before).
When a gun suddenly "can't shoot" and groups become patterns, 90% of the time it's the shooter. The other 10% it's seriously bad ammo or sights about to fall off, or the very odd circumstance that the gun seriously busted. My first is assumption is always that it's me causing any problems.
Human nature is to blame something else. It's ok to admit to yourself you're having a bad day. If practicing the fundamentals doesn't get you back on the right tracks then it's ok to bag it. Bad practice is worse than no practice at all. I've bagged it after a couple mags when I could tell my head wasn't going to be in it. To do otherwise leads to frustration...
And NOW you are sounding frustrated after the fact because you're realizing you had a bad day.... with that in your head how do you expect your next practice to go? This is not the type of problem that a video will capture. Tonight I will post some reading material on sports pshychology and the mental game.
Zen Golf is one. Can't recall the other I've read.
Finally, and most importantly, I'm inferring that you are not calling your shots properly if your groups are opening up 4x and you can't bring it under control. Until you have the ability to know where the bullet went before the bullet even gets there, just by watching the sights, you'll never obtain the consistency you are after.
It was a bad practice. Learn something about your mental game from it.
Let it go. Don't talk yourself INTO a rut. Look at it as a sign you are improving. Odds are you've had those days before, only now you're performing to a level you could observe it in the results. The next level is to observe what caused it (and it's not always technical).
