Ladies and gentlemen. Rifle shooters all. There will be days when you're all ready to train; you've prepared well and have a goal in mind for your training session, but despite your hard work it's all just a pile of poo.
For me, today was one of those days. It happens.
When this happens to you (and it will) check you're not doing something obviously dumb. Fire maybe a couple more shots. If there's no improvement, put the rifle down, tidy your kit away and do something else.
It is often said that practice makes perfect. It doesn't. Perfect practice makes perfect. Practice makes permanent whatever it is you're doing whether well or ill. You do not want to iron in crap technique, so when this happens to you as it happened to me this very evening follow my example: lock the rifle away, pour yourself a nice cold drink and write a blog post about it. Or go for a run. Or do some stretching.
Do not waste your time by continuing to train badly.
