Okay so with the reloading components slowly returning…I wanted to start reloading with .25 acp to start off. I’ve never reloaded before but have been reading my manuals, watching youtube, read “how to reload” manual, got Lee Precision 2019 Revised manual and Lyman 50th Edition manual. Got me press, got me dies, got me 50 grains magtech bullets, got some range once fired brass. I’ve basically got all the equipment to start reloading. What I need to know is what powder should I get start out with reloading .25 acp? What powders do you guys think I should start out with? My guns for testing are going to be my Beretta 950 BS and Astra Cub .25 acp. I know there’s “bulk” powder and then there’s those powder with large granules or flakes for a cartridge this tiny. What powder would be best for the .25 acp? I also acquired the Lee Microdisk, I see that it is discontinued.
 
There are several powders that will do a good job.

Depending on what is available try: (in no particular order) Bullseye, W231/HP-38, AA#2 and in a pinch even Red Dot but it's reported to be dirty.
I was told that if I was to reload .25 acp, I should use AA #2 due to the powder being tinier thus better for small cartridges like the 25 acp. Guess I’ll try to look for AA #2 if it’s not available then I’ll use Unique or Bullseye.
 
What powder would be best for the .25 acp?
The smallest pistol cartridge I load is .380 acp. The powders that meter best for me for loading the .380 acp are Bullseye, W-231 and Accurate #2,#5
I use a Redding model 3 with the micro pistol meter for a powder charger.
I think loading for the 25 acp would be a challenge. I hope I get to try it some day:)
Be safe.

This has nothing to do with your question, but I think it'd be a good idea to start your reloading adventure with a different cartridge.

.25 ACP is a fairly high pressure round at 25,000 psi and the pistols firing it are generally straight blowbacks and not particularly strong or noted for their ability to safely handle overloads.

Most .25 ACP loads have a very narrow "window" for powder charges, usually about 3/10ths of a grain between start and max loads.

I have a little experience loading .25 ACP and it's kind of a PITA. None of my powder measures will throw charges consistently enough in the tiny quantities needed (usually between 1.1 and 1.8 grains), so weighing every charge is required.

Bottom line, I don't think the .25 ACP is a great cartridge to learn reloading with. .38/.357, .45 ACP and 9mm (really almost any straight wall or tapered pistol/revolver cartridge) are going to be a lot more forgiving and much better candidates for your first reloading project.
 
The simple answer, something fast. Most manuals will list Bullseye, W-231 and perhaps a couple others.

Pontificating a bit, Swampman (and # 12) has the answer I would have presented had he not be before me. There are much simpler handgun cartridges to begin.
 
Charge weights of Unique for .25 ACP run 1.4 to 1.7 grain. Each charge must be weighed with a scale.
Stick with small pistol primer for .25 ACP because small pistol magnum primers have thicker cups and more powerful priming compound charges.
The old adage is, if switching from small pistol primer to small pistol magnum primer back off your powder charge by 1 grain.
I don't think my balance scale is all that precise at 0.4 to 0.7 grain.

I have handloaded about 65 or 75 cartridges in .25 ACP. The components are just too small for 73 year old arthritic fingers.
 
.25 acp was the first auto pistol caliber I loaded for.

I've used Titegroup, CFEP, and 700x. I think Titegroup would be my preferance. 1.0 grain. Definately weigh every charge. I simply pour it through a Lee powder through die.

Silly me I bought several bags of new cases. Fired cases clean up and reload just fine.

I've also used a Beretta M950's and M21A's. I'm sure I have over 1k through one of the M950's and it doesn't look worn. I have seen a worn 950 and it was a .22 Short. The frame was worn where the recoil spring rides. The alluminum was just worn away.

I agree with the others that an easier cartridge to start reloading with would be a revolver cartridge. I started with .44 Russian.

Bullseye or AA # 2 would be what I tried first based on how well they meter, then other good metering fast powders.

• There's your answer: A FAST powder that meters really good.

• Thus Unique is ruled out on 2 counts. It is not FAST and it doesn't meter well.

• Additional choices that you can actually buy right now: VV N310, Vectan Ba10, and Clays. My preference is the VhitaVuouri. Here's a 32ACP target at 30 feet, before adjusting the sights...

Well, I had been thinking of loading 25ACP for quite a while, but just didn't get around to it. I load about 8 other calibers. Now after reading this thread, I had to go order the loading dies and some bullets to get into reloading those tiny things. Funny thing is that I used to moan about how small .380 was:rofl:

I hope you've got young eyes, small nimble fingers and a damn good scale! :)

Nope, nope,...yes:rofl: I like the challenge:) and I sometimes make bad choices:)

Actually, I think my biggest challenge will be getting 25 ACP brass.
 
With a Lee turret press and powder thru die I dont have to handle the brass much.

I dont see why the 50 gr bullets are any more trouble than 55 gr .223 bullets.

The slow part for me is just weighing every charge.

I remember reading somewhere that you can just take a case that your loading for and file the case down until you get the correct weight charge for the particular powder and just dip the powder and throw them in, and solder a copper or iron wire to the filed case and essentially you now have a known weight by volume and just keep throwing them without weighing it.(of course check to see if the weight and technique you use is consistent…)

Yes. I just haven't done that yet.
