Load help 7.62x25

[Handshaker]

I have a Polish PPS-43C on the way and want to reload. Anyone have any load data for the 7.62x25?
Any data for h110? I'll be using 100-110 gr bullets. I have quite a few bullets for loading my 30-30 and will use those.
thanks for any info

I use 11.6 gr of 2400 with a 90gr hp in mine. Hornady manual shows 12.9gr of H110 with a 90xtp should give 1500fps, which would be equall to the factory fmj's that I've chronographed. None of my manuals have data for 100gr, but starting load for the 90gr is 10.3gr of H110, max is 14.2 , Under min charge can be worse than over max, so If I were doing 100gr, I'd probably start around 11gr of H110 and go no higher than 13.8. But that's just an opinion, I haven't actually done this yet.
Do test your barrel for diameter. I'm sure you are aware that 30-30 bullets are .308 and 7.62 is .311. If you have a tight barrel you might be ok, if not, you will not likely have any accuracy.

Most standard 7.62x25mm cartridges are loaded with bullets in the 85gr or 86gr range. The heaviest bullets I have used in the similar .30 Mauser pistol (7.63x25mm) are 90gr.

Thanks all. Ya i was kinda thinking about bullet choice and prolly shouldn't use my 3030 bullets. Hard to find bullets these days.

What would you do in my shoes on bore diameter and sizing? My 762x25 barrel slugs at .3105. bullets as cast are.314, I will be coating them. I can size to 311 or shoot as cast plus coating.

I also forgot to mention the brass. Domsestic brass like Win, R&P, Fed, ect, are fine, but beware that mil surp brass and a lot of the foreign brass has a primer flash hole that is smaller and not centered and primers that are crimped in. This WILL break de-capping pins when you try to deprime. So either throw that brass aside or buy plenty of decapping pins.

I haven't used any cast bullets yet, but from your information I would definitely re-size.
I would also make sure your bullets can handle the speed of 7.62x25. I've heard some cast pistol bullets are limited to 1200fps or so.

Coating ups the speed limit and I cast these out of hard alloy, which also helps. If I get an accurate load that cycles the action, I don't need full power in a cast load.

I load 13.5 gr. H110, Hornady 90 gr. (.309") XTP, CCI SPM primers, COL 1.30". Email from Hornady said 10.3 - 14.2 gr H110 with their 90 gr. XTP. Hard to chrono (lots of errors) with chrono at 10 ft , probably due to muzzle blast. With chrono at 15 ft. from muzzle measured 1432 fps.

 

[Handshaker]

Is there other options besides the Hornady? Hard to find any bullets these days, limiting it to one off the shelf bullet is very hard to find.

Check the reloading buy/sell forum here on THR. I've seen some posts there before for 7.62 bullets. If you don't find a post, create your own WTB (want to buy) thread.

 

[Handshaker]

Ya i get tired of looking sometimes, so i found Sierra 8005's 85gr bullets online and got 300 with shipping was 86 bucks and bought 300 starline new brass cases for 76.00 shipped and lee dies turret press for 35. I have plenty of h110 and 2400 and primers so i am good.

 

[Hugger-4641]

One more bit of advice:
Pick out a good sample of finished rounds from throughout your lot and cycle them manually through your gun. I have found that my CZ52 swallows just about every round I load, but my M57 is very tight and if there is any slight bulge or crimp problem, it doesn't like it.

My tt33 chamber chokes on .309 bullets even though the barrel slugs at .310.
It makes it a pain.

Make sure you can shoot cast through it before investing in a lot of bullets.

Yeah. I will size to 311 and then make up a dummy round to see if it cycles.

Does anyone have any load data for the Sierra 85gr RN? Never mind, found it in one of my loading books. Just happen to have a big jug of win 231 I bought in a powder lot from armslist before China infected us...
Brewer, thanks for hijacking my thread...

OP, it's important with 7.62x25 chambered guns to slug your bore and find out what your specific gun is. My Zastava Tok clone slugged out to .312, meaning I can use anything from the .309 XTP's up to the .312 XTP bullets. The benefit of the .312 bullets is going to be increased neck tension, something all these bottleneck pistol calibers need as much of.

Finding jacketed bullets is really going to be your toughest challenge because the caliber just isn't popular enough and is poorly supported by the industry.

What do you shoot? I have all the casting stuff i use for BP but no mold yet for 7.62x25, if you are using hard cast

By the time I got a set of dies we were well into the pandemic and I was hoping primers would come back by now, but that hasn't happened and shows no signs of happening and .312 bullets have also been out of stock all year, so long story short I haven't reloaded a single round of 7.62x25. It's high on the list once I'm able to get the components.

I hate to say this but I wouldn't place any bets and things going back to "normal". There's always a new political, economic, or health crisis every time we look, not to mention the liberals trying to take our 2a rights away. I think this is what it is and will be for the foreseeable future. I would have never considered investing in reloading dies in a small cheap caliber like the 7.62x25. I usually only reload the expensive stuff that's over a buck a round. Times have changed.

Here's the page out of one of my manuals. What i don't understand is why only 6gr of 231? I have seen similar loads on the net with upwards of 10-11gr of h110 or other powders. Why such a difference in Grains? I typically would buy powder that requires the least amount of grains for the same performance to get more loads out of a lb of powder, making it cheaper to reload.

 

[Hugger-4641]

Here's the Hornady 10th , only bullet they list, but look at the velocity difference. The Lyman data is only listing the slower powders and loads. This is why you need multiple manuals, and check against the powder manufacturers data.

 

[Handshaker]

I get it, I just get a little paranoid loading a case with a minimal amount of powder, I know this isn't the same thing as loading 45-70,3030 or 243 as this is a small case to begin with. You have to be careful with larger cases and low amounts of powder in them for them not to become a hand grenade...

 

[Hugger-4641]

Pistol is worse than rifle, especially with double base powders. They don't like under charges.

 

[Handshaker]

I was able to cancel the order for the Sierra's. i found a guy with 700 of the hornady's, I'm buying those instead because of all the load data for them.
