I only have one Browning 1885, but I have (3) Ruger #1s.
The 1885 requires the hammer to be cocked.
The 1885 requires the case to be partially manually extracted.
A big scope eyepiece gets a little in the way of cocking the 1885.
That means that from a prone position with an ammo belt cheek rest, the Ruger #1 can be fired fast like a semi auto, and the Browning 1885 cannot.
Both are beautifully machined.
Both are more accurate than I expected.
Both are a joy to own.
