But you only know how safe something really is if there's an accident. It's difficult to create a flowerpotting shell in a controlled test.

I haven't actually seen the full article below, as you need to pay to see it - but it looks interesting:

Not difficult at all. Remove the lift charge from the shell (making sure there is passfire to the timefuse of course), and voila, instant flowerpot. Another obvious way, load the shell upside down

This is the kind of test anyone designing racks should do - in a suitable location (I would say 200m safety distance to be safe) with remote firing or a LONG time fuse of course. It certainly taught me a lot about what works and the awesome power of what we use.

Ok,

I tried 6 x 3" in a row with the quick match spliced open a bit and put into the next tube and taped over the top.
1 e-match on shell one.
All fired in less than a second and was a really nice quick way of setting up a finale run of shells! I like it, i am going to try next time with some knots to see how much difference it makes. In all i think due to the speed it was pretty safe.

Nice one! Glad you tried it.

Like I say the main advantage of this method is the speed of fusing "in-the field". As always the main thing has to be safety, which is why peer review is such as valuable tool.

Let me know how the knotted leader technique works! Video's always welcome....

Did you test a single shell failing in an otherwise empty rack, or a shell failure in a fully-loaded rack? I'm fairly sure you'd get a different result.
