Too bad those are even harder to find than pistol powders! Have not seen any clays for more than a year!

Re: pistol powder bulk
Each smokeless powder is different. They are assigned a "Burn Rate".
Pistol powders are on the FAST side of the burn rate chart as most pistols have short barrels. The must propel the projectile quickly and only have a short amount of time to build pressure needed.
Rifle powders are on the SLOW side, since they typically have longer barrels and need the powder to continue burning down the length of the barrel to build more pressure.
For example HP-38 and Unique are FAST and have burn rates of 28, and 31 respectively. Magnum powders such as H-110 burn slower with a burn rate of 62.
In comparison rifles such as 223 Rem use slower powder such as Varget (BR 99) and B-LC2 (BR 102). Magnum rifles use even slower powders such as H-4831 (BR 125).
It is a generally a BAD idea use rifle powder in a handgun load, and vice versa. A few exceptions do exist, such as low power rifle loads with lead projectiles. I have used Unique and 2400 in some 30-30 loads with cast projectiles.
It is a good idea to read several loading books as most of this is explained much better than I can do in a short time!
BE CARFUL!
