If you use RCBS cowboy dies it's not so bad. Originally the 44-40 was sized to .427. Modern 44-40's are sized to 429. Most reloading dies still size to .427. Trying to shove a .430 bullet down a thin .427 case neck results in a crushed case. The cowboy dies size to .429. If you have dies from another maker you can use a .44 mag expander plug or what I do is use a wad punch to bell the case mouth a little more.
