I have been messing with an antique 44 so I picked up FFFg powder and learned a lot more about blackpowder and how to go about reloading and shooting it.
It got me thinking about grandpas 25 Stevens rimfire rifle, it is a bolt action boys rifle, an Eatonia from the teens or twenties.
I did some digging to figure out a parent case and a lot of people talked of the 27 cal nail gun blank behind #2 buck shot or an air gun pellet but this only really works in a hinge action and the powder is a smokeless with a lot of pop that can do some real damage to the gun.
The 17 Winchester Super Magnum ($20/50 or $0.40 each) are based on the 27 cal nail gun blank with a length to the shoulder about half way between the 25 Stevens short and 25 Stevens long, the case is 10 thou smaller in diameter but the rim is the same diameter and since it seals and headspaces on the rim I should be good.
I picked up a box to see if they would even chamber and after cutting the case at the shoulder then do, the extractor fits great over the rim and although it took 2 strikes the firing pin did fire off the primer with no powder.
Here is a picture of the cases, from left to right, 25 Stevens Long, 17 Winchester Super Magnum, case cut at the shoulder, 25 Stevens Short.

The original loading for the 25 Stevens Long is 10-11gr Black Powder with a 67gr bullet, the 25 Stevens Short was loaded with 4.5-5gr Black Powder behind a 65gr bullet, the Black Powder was replaced with smokeless but since there is no set rimfire powder and the stuff back then may have been different I am looking to FFFg as my powder, sure I will have to clean it but cleaning it means I am able to shoot it again.
I took the 0.5cc dipper and leveled it off with FFFg and tossed that on my RCBS scale, the load came out to 7.5gr.
Here is a photo of the load in the case.

The plan is to find soft lead .251 bullets, I would like to get 65gr but I have seen 50gr for 25 ACP, they should work fine. The biggest issue is getting the ally right, Bullet Barn has the size but I am not sure if they can cast soft for me. If not there is a place in the US that sells airgun pellets at this diameter with a hollow point at 48gr and a flat point at 49gr for about 10 cents a bullet and they an ship these to Canada.
I plan to get 25 ACP dies, remove the decapper and since I am iffy about putting the rimfire rim in a rim held shell holder I think I will make a custom shell holder that I can just set the case on when flaring the case mouth and seating a bullet.
Things are coming along.
