I have a very limited understanding of hft shooting. This vid has given me an insight. I've also seen the many arguments about hft shooters vs hunting shooters. One observation I've made is the amount of time to settle into shots and the ability to fidget for comfort. Whilst I do understand why the hft shooter does this, most of the rats on my permission would have left by the time each shot is taken and would have been spooked by the movement of the shooter.
That said, nice groupings, mate.
