Quick Bore Sight Procedures before zeroing a scoped rifle

If you dislike spending more time, effort and resources for zeroing, it is a good option to conduct quick boresight procedures before the live firing activity. The techniques are published in various manuals and discussed in many internet forums. I took a video of my own pre-zeroing procedures which include aligning the bore and the scope reticle towards the same direction. Imagine a 'cross-hair' inside the bore, point it at the center mass of your target (preferrably, a big one like the military silhouette),  compare the sight picture with the one you see in the scope. Make adjustments on the scope until the reticle and the imaginary 'crosshair' of your bore are in the same aiming area.
