Here's a challenge for you
I really need to improve my standing shots (and, quite frankly, the rest of them as well). To that end I'd like to have a technical means of measuring and recording the stability of my stance when using different positions and holds.
Now I know one answer is simply "try it and see", recording the effectiveness of different stances simply by the groupings achieved on some sample targets - but that means going outside into the nasty cold and wet weather - which is also rather windy and which would thus add an unwanted variable into the mix.
So does anyone know of a relatively simple and cheap means of recording the movement of the rifle's barrel during the aim and fire sequence, something perhaps involving a smart phone, a laser pointer and a lump of chewing gum, or similar.
