Quite how this match finished goalless will remain a mystery for a long time to come.
Following on from the draw at Crystal Palace prior to the international break, Rangers yet again dominated a Championship fixture, but were left with only a point to show for their efforts.
Missed chances, fantastic saves and the intervention of the woodwork on no less than four separate occasions turned a potential goal-fest into a stalemate.
Akpo Sodje headed against the bar in the opening exchanges, before Rangers rattled the woodwork twice in as many minutes before the break.
Scott Sinclair fired an effort off the post, before Mikele Leigertwood's header bounced back off the bar, with the Owls defence all at sea.
The theme continued in the second period, with Burton O'Brien smashing a stunning effort off the stanchion, while at the other end, Sinclair was denied on no fewer than three occasions by the outstanding Grant.
The Rangers starting XI showed two changes from the 1-1 draw against Crystal Palace a fortnight ago.
Luigi De Canio handed a home debut to Derby County loanee Bob Malcolm, while Dexter Blackstock returned form a seven week injury absence to partner Rowan Vine in attack.
Owls boss Brian Laws opted for the front-pairing of Sodje and Marcus Tudgay, for a Wednesday side unbeaten in six matches.
On a bitterly cold afternoon in W12, it was the industrious visitors who created the first chance on seven minutes.
Yoann Folly's near post corner kick was glanced on by Sodje, who saw his effort bounce off the underside of the crossbar.
Damion Stewart was in the right place at the right time to clear the danger, as Rangers escaped unpunished.
The one-way traffic continued, with Tudgay seeing his goal-bound effort deflected wide, as the Owls set up camp in the Rangers half.
Wednesday's pressure was relentless, with the lively Sodje racing on to Frankie Simek's 13th minute through ball, rounding Malcolm, only to fire straight into the arms of the grateful Lee Camp.
Play quickly switched to the other end, with Vine sending Sinclair clean through.
Lee Grant darted from his line to meet the Chelsea loanee head on and it proved to be the right decision, as the teenager fired straight into his midriff.
Buoyed by that opportunity, Rangers were on the attack again moments later.
Martin Rowlands' neat reverse pass found Vine, who took one to set before slotting past Grant. The Birmingham front-man wheeled away to celebrate, only to see the referee's assistant flag for offside.
The R's were well on top by now and Vine brought the best out of Grant with a fearsome 25-yard strike after linking up well with Blackstock; before Buzsaky sent a dipping volley inches over the crossbar.
Akos Buzsaky continued to impress in the heart of the R's midfield and when Blackstock teed the Hungarian up on the edge of the box, the new darling of the Loftus Road terraces jinked one way and then the other, evading challenge after challenge, before seeing his shot diverted wide.
Buzsaky played provider on the stroke of half-time, spraying an audacious pass into the path of Sinclair, who bore down on goal before smashing a fearsome right footed drive off foot of the post.
From the resultant corner kick, Leigertwood's looping header bounced back off the crossbar, before being hacked to safety by the desperate Wednesday defence.
The attacking nature of the match continued on the resumption, with O'Brien stinging the palms of Camp, before Vine's searching cross was deflected wide via the outstretched leg of Richard Hinds.
Vine went close again in the 50th minute, running from deep inside his own half before exchanging passes with Sinclair.
Grant was again in the right place to save his effort though, this time tipping the ball round his right hand post for a corner.
Remarkably, Wednesday struck the woodwork again on the hour.
Gifted time and space out wide, O'Brien - after being set up by Tudgay - unleashed a powerful curling effort, which had Camp beaten all ends up. Thankfully for the hosts, the frame of the goal again denied the visitors.
Chris Barker's roaming run and cross found Sinclair on the edge of the six-yard box in the 65th minute, but yet again Grant was there to deny the R's, flinging himself full stretch to his right.
The Sinclair versus Grant battle continued apace as the clock ticked down, with the latter pulling off his best save of the match 17 minutes from time, as the tricky winger fired low and hard to the goalkeeper's right.
