Well after hunting through the FAQ on http://www.mordheimer.com/articles/FAQ.htm#11._Experience
I found,
Q: The Quick Shot skill allows a model to fire twice per turn. Can a model armed with a sling and having the Quick Shot skill then fire four shots if they are less than half range?
A: No -the spec. rule and the skill do the same thing. They both change A into B, doing the same thing -end result is the same. No doubling doubles! [Tuomas, Mordheim Yahoo! eGroups' FAQ]
However there's nothing in the GW FAQ about it, I feel that this ruling may be appropriate, let me know what you think Ryan.
