I picked up a nice 1873 in 11mm awhile back and have been collecting reloading info for it. Planning on reloading for it this coming winter so any of the following info I’ve gathered for it is from different sources and different people.
Feel free to make observations or corrections as I’ve only collected this info and haven’t tried any of it yet.
11mm 1873 French Revolver Reloading Info
Original BP cartridge .71 case length
1.18 loaded length
.452 dia, 11.7g (180gr) lead bullet with a .430 heel
0.65g (10grs) fine black powder
Bullets .452 (190gr) lead with a .420 heel from Jethunter (tumble lubed w/ Alox)
Some use a 230gr bullet
Brass 44-40 Win cases
Rim is .525 dia
Rim is .065 thick (trim to .040)
Case length (trim to .71) (one guy suggested .74)
Use a Lee case expanding die to open the neck
Note: Buffalo Arms sells cases made from 44 S&W Spl and The ID
of the brass is approx. .419 and will need to be expanded
Case Prep Lee shell holder for case trim kit #14
Case length gauge for 44-40 is too long (modify to correct length)
Custom Case length gauge ($15 in 2013)
Decap Universal decap die (I have one)
Prime Use #14 shell holder (for 44-40 case) and Lee prime tool
Use #11 shell holder (for 44 pl / 44 mag case)
Large pistol primers for 44-40, 44 spl and 44 mag
Press One guy says to use a 44 spl die to seat bullets but 44 spl are .430
One guy says to use a 44 spl die to seat bullets into a 44 mag or spl case
One guy says to use a 45apc die to deat bullets in a 44 spl case
45apc bullets are .452 so that might be better
454 Casul is .452
45 LC is .454
Powder BP or Unique for smokeless
Lee dipper kit and funnel
Lube Use a BP lube if using BP
A 45-70 case is a perfect cookie cutter for .452-3 pan lubing
Dragon Bullet Lube (Richmond Hill) has BP lube in cylinders
