Keep in mind (

Smokeless powder
(2) Smokeless powder must be stored in its original container or in small arms cartridges.

Detached dwellings
301. The maximum quantity of propellant powder that may be stored at any one time in a detached dwelling, or in a storage unit attached to a detached dwelling, is 25 kg of which no more than 10 kg may be black powder.
Other dwellings — smokeless powder
302. (1) The maximum quantity of smokeless powder that may be stored at any one time in a dwelling other than a detached dwelling, or in a storage unit attached to a dwelling other than a detached dwelling, is
(a) 20 kg, if all the smokeless powder is in containers that hold no more than 1 kg; or
(b) 5 kg, if any of the smokeless powder is in a container that holds more than 1 kg.
So, basically, even if Higginson sent the powder in 24x1lb containers we couldn't keep 2 shipments of powders from Higginson in a non-detached dwelling.
That being said, with 24lbs of titegroup I can make over 40,000 cartridges. That's a lifetime supply for a lot of shooters. And that's about 800lbs of ammos to store somewhere. Not only that, if I just want to try a new powder for a cartridge, ordering a single pound from Higginson if out of question.
I'll stick to xreload, western metal, canam's D4064 (if they bring it back), and Henry's. Plus my LGS when they go on sale.
