What did you build yourself

[JoshIronshaft]

I had never shot a mortar, or even seen one shot in person. I wasn't sure if this was going to be "worth it" or fun, now I don't know how I lived without one!

Here's 2 videos of the 81mm mortar firing: https://imgur.com/a/ylFGqYc

First one is slow motion and short range.

Second video is 86 yards.

Data from trying different amounts of Bullseye pistol powder, all at a 45 degree barrel angle:



So now I'm going to use 32gr at different barrel angles to make a firing table.

The shotgun hulls after firing, holes are from the gas venting out the holes in the fin tube. To load the launch charge you take a 12 ga shotgun fired hull, replace the primer, pour in the powder, then pack it completely full of fiber wads. That's all there is to it.



This one was at a shorter distance, further out they almost completely bury in the semi dry ground:



I got an NSB-1 sight for it, which I'm still trying to wrap my head around, but so far the rounds land where I point them.



Welded up the lower holes in more dummy rounds to make them ready to fly.



Oh, and I painted the CETME L.
