P.M., the 44-40 is really not that hard to reload for IF you are using the correct method.
As I'm sure you know, there is no carbide sizing die for BN cartridges, but most don't need one. In fact I NEVER resize as all my chambers are pretty much standardized.
1. Deprime BUT do NOT resize.
2. Reprime and lightly bell case mouth.
3. Drop powder & seat bullet to correct depth but do NOT crimp!!
4. Lee Factory Crimp Die.
Steps 3 & 4 will eliminate any bad reloads, e.g., crumpled case necks.
