I'm sure
Last 2 1# cans off the shelf at Recob's; made in Australia.
I got an 8# jug off the shelf at Recob's last spring. Made in Australia.
I didn't say All IMR 4227 was made in Australia just that the last ones I got were.
I can't find any manufacturing date on the cans.

Now that Hodgdon is selling all these, it would sure make things easier if they would just market one version of each.
I suspect they are headed in this direction.
Eventually they will all be "extreme" versions as well (polishing up the crystal powder measure).
