Look at the side plates and the gun's scale.  The rifle in the photo is a Model 1873 (and not a Model 1876).

For your new barrel you may wish to select the correct length bullet for your new barrel twist.

Here are the gyroscopic stability factors (Don Miller Sg formula) for 50 caliber bullets for each barrel twist:

Bullet                    Weight        Length      1:36      1:34      1:32      1:30      1:28      1:26      1:24      1:22      1:20

You need enough spin to stabilize a bullet so need an Sg of at least 1.4 but 1.5 is preferred.
Bullets overspin after an Sg of 2.0 but long range shooters select bullets up to 2.4 to overspin bullets to compensate for drag over a 1,000 yards.
Excessive overspinning is believed to affect accuracy.

Do not discard the bent barrel.
It can be straightened by a good barrel maker and someone may wish to have an original barrel.

Very nice rifle, Dave!

Yours still looks original. Looks good.

The .43 Spanish had an extractor for a .640" rim.

Where did you find a narrower extractor for a NYS for the .608" rim of your new .40-65?

With the split trigger on the NYS you cannot replace the trigger spring with lighter piano wire spring.

I tried to make piano wire springs for the split trigger but it resulted in too much trigger creep.

To lighten mine I made new flat trigger springs from hack saw blades and still had to angle back the sear and reharden it.
The middle is an original spring - and I narrowed the roughed out springs until I found a pull that was acceptable.

The NYS receiver is different than the other No. 1 Rolling Blocks.

Has he ever done a NYS Rolling Block?

Their split overlapping trigger is quite a bit different than the majority of Rolling Blocks with one piece triggers.

I'm sure Curt can get your trigger to a great trigger pull.  He does meticulous work, some of the best in the business.  When it leaves his shop, it will be right.

You can replace the trigger spring with a piano wire spring on a NY contract action, though.  This came up a few months ago, people insisted it wouldn't work, so I made one for George Babbits and sent it to him to prove it could be done.  I think it only took me one prototype and one working spring before I got it to work.  It had a bit of creep to it, not too bad.  I could eventually figure out how to make the spring non-progressive, and to work on the split sear uniformly, to remove that creep, but for as few of these actions as there are out there, I doubt I'll ever mess with it.  I have a few of these actions, and a rifle built on one, I used a wire spring in mine 20 years ago when I built it.  I took it apart after I made the spring for George, and I had done it a different way; didn't even remember I had put a spring in it.
