Brent that rifle is looking good.
The aperture sight looks shop made, pretty cool detail.
Describe the shooting performance. Maybe we can put our heads together and help you get it running right on the targets.
Have you slugged the bore?
What loads have you tried?
I'll have to get my books and check but a gas checked cast bullet (>210 gr, "Krag bullet") and 5744, which I do not like at all. Just isn't accurate.
The aperture sight is a Pacific sight.
The barrel is in beautiful condition and an original barrel with the rear sight screw holes very carefully and artfully filled. I didn't know they were there until I discovered it was an original barrel and started looking real hard to find them.
It has been a while since I have shot this gun, so I can't quote more details without finding my books
