To answer the original question, lots. Samples:
All-out run @ ~150yds:
Rutting/trotting behind doe @ 300yds:
Full-run, 125yds:
Flushed from cattails, full run, 200yds:
Full-run pard had missed him twice, 275yds:
Full-run going almost dead away @ 100yds. Looks gut-shot, it was't. In behind the "knee" out just inside of it, back into the chest just behind the last rib and I found the slug under the hide on the off-side shoulder.
There are a bunch of does, at least one more bull elk, and a truckload of coyotes as well.
