I switched a long time ago from the Winchester powders because they kept deleting powders without any replacement. Hodgdon has them all - if there is a cartridge made you can find the best powder for it at Hodgdon!

H110 is W296....
I`m pretty sure H4227 has been discontinued. Hodgdon likely will offer data for some time to cover the powder that is still out on the shelves or in customers hands.
Hodgdon now owns IMR powder and they would be the best source for your question. They should be able to tell you if data is interchangable between the two, or if not, offer data for the IMR line.
Hodgdon now is the distrubutor for Winchester and I heard VV powders. They should offer help/data with all powder 4 brands now. Hodgdon, Winchester, IMR, and VV.
