Not being able to find H110 has allowed me to learn how little use I really have for it.
One of the things I've always like about 110/296 is how easy it is to use; load heavy and it shoots well!
It troubles me that my latest 8-pounder is down to a trickle, but I have enough loaded heavy loads for the 44 and 45 revolvers to handle my 'needs'. I just don't have enough to go out and shoot that powder up so I have to resort to whatever I can find. Caught a pound of 800-X a few months ago, and a pound of HS-6 recently. Pistol powders are still scarce.
