While I wouldn't describe properly zeroing sights as a wasteful use of ammunition, correct and precise boresighting (centering on a target 40-50m distant down the bore visually - those laser gadgets can be and frequently are somewhat misaligned themselves) will usually put POI somewhere between beltline and collarbone on a fullsize silhouette at 150m with most rifles.
Should be perfectly workable then. IME a good boresight job will be within 2-4MOA of actual live fire zero more than half the time, and unless something is seriously wrong with the weapon like a warped barrel will almost never be far enough off to be ineffective at close range.
