Stormcaller said, "...resting a weapon on a window sill is bad form for any rifleman, let alone a sniper. It exposes your weapon, and it can be seen from below and to the sides, not to mention, exposes you more."
Roger that. Good point. The main point was that somehow the rifleman or sniper will find a way to steady his weapon, even if it's just tucking his off-elbow into his chest, which works well if you can't have or don't need bench-rest accuracy.
But that is not an issue anymore. I don't know what happened, but now I can steady the breathing bob while standing. I was certain I wasn't able to, before. Did you just fix that Yurch, or was I hallucinating, LOL !?
