Patrick, I posted on another of your postings today but I had to add what I know on this one. First I have shot the 44WCF cartridge for several years starting in the 70's. I have shot this caliber in SASS shooting since 2007 in the Frontier Cartridge class because as far as I'm concerned, I feel it's the best cartridge ever designed for shooting the real Black powder that it was designed to shoot.
This cartridge was never meant to shoot 225 grain bullets, stick with the 200 gr class bullet. The Lee REAL bullet was never meant to be fired in a cartridge case, it was intended to be fired in a muzzle loader from the front of the barrel.
There also has been a lot of talk about the different sizes on the 44WCF guns, that is not the fault of the cartridge but the gun makers who build guns for it.
Marlin and Ruger are two great examples of what I'm speaking about. Marlin decided to build all of it's rifles in 44WCF with 44 mag barrels that had .430 bores. As we all know, the standard that was set for the 44WCF is .427. Marlin only had to make one size barrel for all of it's 44 guns, a decision by a bean counter most likely. Ruger has been all over the board on this caliber with some of it's guns being too small and others being too large. They had persons who had Ruger revolvers with cylinders that were .428 and bores that were.430, that does not work well.
Now for my next little bit of info. The 44WCF was brought out in the 1873 Winchester lever action to be an answer to Colt's 45 Colt in it's SAA. It was never designed to be a high pressure cartridge to get 44 magnum results from. A smokeless load of 8 grains of Unique will give about 950 FPS as will the original load of 40 grains of BP will.
The best case to purchase is the Starline as it will outlast all the others by many loadings and they are much cheaper than Winchester or Remington.
I know I can't help you by sending you any cases but I may be able to send you plenty of info on loading for this cartridge. I was a Firearms Instructor and Armorer for a very large Police department and know that since the Twin Towers, all of the rules have changed. I will look into it and see what I'm allowed to send you if you are interested. PM me with your info. Take Care David
