I could see two possible problems. The main one being that brass ejecting forward would make it nearly impossible to retreive your brass at some indoor ranges. Also isn't 5 feet a bit far to throw brass?
First, remember that the guns are meant to group BULLETS, not brass. That said, consistent ejection is important to reliability. The actual direction of the ejection is largely determined by the interaction between the brass, ejector, and extractor. The nose of the ejector can be reprofiled a bit to let the brass roll off to the right and upward. If looking at the ejector nose, ie. the frame is pointing TOWARD you, you'd lightly bevel the left side of the nose and cut a little angle into the 10:30 corner of the ejector. You can also get away just fine without profiling the ejector at all. I usually cut a harder angle on my 10:30 to ensure good rollover on ejection. If your gun has a stock ejection port, the angle of ejection may well be limited by the size of the opening available. HTH
