Tierhog,
Speeking from the standpoint of collectors: If you shoot it, you ruin it's collector value. Period, end of discussion.
Especially with the manufactured collector guns such as yours. They have little value to start with, so any shooting just reduces it further.
However, since it is your gun and you want to shoot it, go for it. I'm not a collector and I shoot all my guns.
However one suggestion. Based on experiance, (I had a Golden Spike) and what I've read on the boards, I'd have it thoroughly checked out by a competent gunsmith familiar with Win 94's before I shot it. Some of the commemorative seem to have been assembled with parts from the "out of spec" bin. So a good check out won't hurt.
