Knok:
I used to spend about 3/mo out of the year at the OTC in Colorado Springs. We also had most of our trial competitions either there or in Georgia.
It was kind of fun shooting in the foot of NORAD, though after 9/11, the security kind of tightened up and made things a bit more interesting for us once when we got lost on base on a road that went ponderously close to a live fire arty range. :/
We were sponsored by Federal for ages. They loaded us skeet shooters an 8 1/2 shot 7/8oz copper plated paper hull load that would shred the targets. Not to mention the hulls smelled great (huffing too much smoke probably explains a lot nowadays).
Seems like a great range/setup you've got there mate. Hopefully I can make it out there eventually and tour the place.
@DD yep, I like to stay prepared.
