Remington No 1 Creedmoor

[Fogman01]

The whole chamber is larger than a standard Shiloh 44-77 case but not longer. The chamber cast showed a 2 1/4" case but larger dimensions for the base, shoulder and neck. When I fire formed the brass by shooting the rifle, I tried to put the cases into my Shiloh 44-77 and no go. I could probably re-size them if I wanted to but I will just shoot them in the Creedmoor. The chamber allows the bullet to be seated all the out thereby allowing 90 grains of powder to be loaded into the 2 1/4" case like they did back then. I do not put that much in it (just 70 gr of Swiss 1.5) and I use a grease cookie and wads to fill up the extra space. I don't know what an original Sharps 44-77 chamber is like but others have said their original Remington 44-77s are a bit larger than the modern versions.
