An interesting bit of Automag trivia is that the IHMSA organization grew out the earlier Club D'Automag. The silhouette game was intended for automag shooters, but turnout wasn't as was hoped for. So, those early South West matches opened up to other shooters. This was the very early 70s.
I seem to recall that the original intended distance for the rams was 300 meters, not the later 200 meters.
I wonder what the impetus was for the change? I could see where the Automag would have a decided edge at that longer distance.

Good going to the OP.
Beemer1, nice one you got there, too!
Anyone else have some more cool pics?
