Slowest burning powder available in Aus

[Sionso]

Is there a powder available in Aus that is slower than AR2218?
I'm trying to hunt down WC872 or slower. Something suitable for 20mm... (any 20mm suitable loads are fine IF the powder is available in Aus). Current problem is AR2218 doesn't take up enough space in the case and i really domt want a flash over in that size.

Would VV 20N29 work for you?

[No1_49er]

According to the ADI powder equivalence table, VV 20N29 is the equivalent of AR2218. Not sure that it would work any better.

Maybe use a filler medium to occupy the space.

Why not? If you can have .700NE, 14.5mm, 20/50, why not have '.78Super' (percussion primed 20x110). NT and Vic are generally fine with large cal rifles.

Seeking such a slow burning powder for a .78 implies it is not simply a glorified metallic cased 12 gauge but something with a magnum sized case capacity to bore ratio more along the lines of some kind of 20mm cannon.
Any sanely dimensioned man usable .78 would require much faster powders.
Or it could be that you have limited understanding of what you are talking about, hence the question posed.

I think he is talking about the 20mm cannon round, but replacing the electrical primer with percussion. It fires a 1700gn shell at 3300fps or so. I'd be very surprised if this were legal anywhere in Oz.

G'day Sionso,
In regard to your original question, no, there is no slower powder readily available to the reloader here in Aus. You will need to use AR2218 with a filler of some kind if you are concerned with double detonation, Cheers

That was my last resort plan, looks like the only option unless I pull a few of my old cannon shells apart.

Correct, both people i talked to at LRD couldn't see any issues with it as long as it wasn't a military cannon round (which technically it isn't).

Why do they consider it not to be a military cannon round?

[TassieTiger]

Cause it’s pink?

G'day bladeracer,
20mm is considered ammunition under UN Class 1.4s, it is approved by LRD for small arms ammo collectors to possess without being rendered inert. Cheers.

[No1Mk3]

PS: For the formal - minded, info is in the Act, Sch 2, S.7, Sub-Sect (3), para (a) of V.82, Cheers

I wasn't asking about the ammo. I'm asking why the Police would consider a military cannon round to not be a military cannon round.

To to OP, have you had a PtA approved for a firearm in this chambering?

But, regarding the ammo, can you collect live ammo that has explosive warheads?

[sungazer]

There is a big difference to being allowed to own the ammo under a collectors license. Factory and historical. But to reload the round implies that the round is being shot. This I think is well outside what is covered under the small arms.
