It seems that very few people these days load and shoot the .25-25 Stevens. I recently joined the ranks with acquisition of the Stevens model 44 discussed here:

I posted some initial loading tests in that thread. But rather than muddy the waters, I thought it a good idea to start a discussion here in the reloading forum focusing on loading and shooting it. This should make it easier for others to find this discussion in a future search.

To recap and kick it off, here are my first loads:

I tested a few loads, all with the same 72.5gr, 30-1 plain base bullet from an Arsenal mold and CCI 450 primers.

16.0gr of Blackhorn 209 - 1846fps avg.

22.0gr of APP 2F - 1932fps avg.

Duplex load 2.3gr if 2400 under 22.0gr Schuetzen 2F - 1645fps avg.

A single round of 11.0gr of Reloader 7 - 1556fps.

I think this bullet is too soft and light, but its all I had. I have since ordered some 85gr bullets from the Bullshop to try out. I'm using old UMC brass, but also ordered 40 pieces of brass from RMC. To my surprise, they had it on the shelf ready to ship 

More to follow!

I have had your bullets cast for a couple days. I am waiting on the note with your payment so I know at what diameter you want them sized otherwise they would have been ready to ship.
Look like a long one there.  I will be interested to hear how they did with black horn powder.  That brings up another point of weather you want your bullets lubed for black powder or for smokeless powder.

Ping for later.

You must live right.  Or you ordered before I did.

Check your neck wall thickness.  In the past I've found a couple of RMC .25-20 cases that were paper-thin on one side.

Your new brass looks good. I’m most curious as to what you come up with for smokeless loads.
While I don’t have a .25-25, I do have a.25-21.

FWIW, I checked case mouth expansion on one of the UMC cases I fired and it was minimal, maybe .003" at most. Very pleased with that.

I was expecting your payment today but it has not arrived yet.  To expedite this to your project please let me know the mailing address for the bullets and I will get them shipped.  If the payment is lost in the USPS void we will work that out later. I want to get these to you because I am anxious to follow your progress.

The Missus got them labeled and is headed for the PO with them no
