Answer to the Challenge.

Oddly enough, none of the usual characters were players this time. But we did have a new crop, two of whom got the right answer! Here's the original post.

Martin got in with the first correct answer, and Neil came in with the correct answer too, after thinking about it across a couple of emails.

Here they are, with a 12 Gauge blank for scale.

High res shot is here if you have the bandwidth.

Here's the 81mm, standing next to a round. Inserted. High-res shots here and here.

Here's the 60mm, standing next to a round. Inserted. High-res shots here and here.

These are WWII primers, made by Winchester. They look just like shotgun rounds, and are made the same way, but have a different, hotter burning powder in them.

Thanks to those of you who chose to try (or got there in time, as I know some of you were traveling this weekend.

So they fired the main charge. Cool. I never knew that. Better then designing a whole new primer system. They used what they already had. I knew they looked just like shotgun shells, and for a second I thought they may have been something else, but you are not into airplanes so I threw that idea out.
 
Gunner - I am too into airplanes! But no, you're right, those aren't starter cartridges... And I goofed in the post. That's a 10 Gauge blank, for my Winchester signal cannon, which got a workout on the 4th! Ah, the smell of gunsmoke!
