If you have a good reticle (read "ranging" reticle), its a trivial matter. Measuring a miss with it, then correcting on the turrets is SOP when you're running an FFP scope, but it can be done with an SFP scope if its on the right magnification setting. Whether you're correcting for a bad wind call, a bad distance call, an unknown distance shot, a change in environmental conditions or a zero offset from removing and re-installing the scope makes no difference. The procedure is the same: measure with the reticle and correct directly on the turrets. It's something you're already doing.
This is one of the reasons why "ranging" reticles and exposed (prefereably locking) turrets are of value even in low power SR optics (new Leupold, Premier and S&B 1-8x scopes have these features). If you lose your zero for whatever reason, you can perform a field expedient sighter (like in the 500m PR match) and get a decent zero. You can do this in a match, you can do it in combat. It only takes a shot or two and you just need to know the approximate distance, have something to aim at and be able to see the hit. A sandy hill, concrete or brick walls work for this at distance... at close range you can see bullet holes in things through the scope. Fire a shot, then use that splash/pot mark/hole as your aiming point and fire a second shot. Then adjust and reset the turret to what is should be for that distance (those scopes allow you to do this in seconds without any tools).
