Have been playing around with H110 too, but I'm not sure what I think of it yet, and wouldn't recommend it, as it seems to produce high pressure quite quickly in bigger cases.
H110, and Win 296 which is the same powder, is/are not a good choice in reduced loads. It only burns well at near full capacity and at full pressure. Winchester used to publish a warning in their .357/41/44 Magnum data"
"Do not reduce powder charges with 296 Powder. These loads must be used exactly as shown. A reduction in powder charge or change in components can cause dangerous pressures."
I have burned many pounds of H110/296 in .410 bore skeet loads and also use it in .30 Carbine and .300 Blackout loads.
