Data for 125 gr 38/357 lrn

[savagelover]

Have on order a 125 gr round nose mold (lee) for use in my Rossi 92. Going thru my manuals I see no mention of a 125 gr cast bullet. Anyone have any info or can I use jacket bullet info. Thanks.

 

[Seedy Character]

I used jacketed info and start at the bottom.
I shoot a lot of lead bullets, mostly in cowboy (light) loads, but occasionally hot rod some, for fun.
I used 2400, 4227, 4756, 800X, Unique and Trail Boss; with good results.

Appreciate your reply. Thanks.

Hodgdon has almost all of their faster to mid range powders listed with data for a 125 cast bullet. I believe Lyman 49th also has a 125 cast in their data.

Alliant also has 125 cast data, but only for Red Dot and Unique in their "cowboy" section. I did not check their regular .38 data.

This is in the Lyman #4 cast manual

That is a great bullet. It is one of my favorites.

Take note of the alloy and pressure. At even the max load listed a lot of powders are not in their happy place. Those velocities are also at pistol lengths so choosing a lube if your not powdercoating should be based on a higher velocity.

Which powders do you have available? Are you planning to use .357 or .38 brass?

Since you're working with a carbine-length barrel, take a look at .357Magnum data for the Super-16 or Super-14 Contender starting loads. Stick to mid-to-long burn powders. Unique and slower should do you right in a lever-carbine.
The Complete Reloading Manual for T/C Vol. 2 lists the 121gr. cast.


These were tested in a 10" T/C barrel, 1:18" twist, and CCI 550 primers but there's no real reason to use SPMP with either Unique or 2400.

My 38spl+p+ 125gr cast lead load (for use in 357mag rated guns) uses CBI.

Thanks for all the replies. My mold should be here tomorrow. Just wish it was warmer as I cast on my little shed.

I think you're going to really like that bullet.

I have a nice load with that bullet (powder coated) and Titegroup (only load I use that powder for) for an old Ruger Security Six and a S&W 642 and I'm currently in the market for a .357 lever rifle that I am hoping that bullet will shoot well through.

My only problem is that I bought the double cavity, I really wish I would've got the 6 banger!

 

[savagelover]

I thought of the six cavity but for an old man a double will work. I had a Henry in 38/357 and a Rossi. I still have the Rossi still. Lol

 

[savagelover]

Silly question. Do you think there is much muzzle velocity between the round nose and the round flat nose bullets.

No and at short ranges the bc won't matter... shooting over 100 it starts. That's the premise of the lever revolution rounds...

I have shot a lot of the Berrys bullets plated 125 gr using the Hodgdon loading data online. Makes a nice load. I have shot round and flat and HP and see no essential difference in how they shoot. I do not measure velocity.

 

[BJung]

I am in need of reloading data for a 38-125gr cast bullet too. The load data I've collected is 3.6gr-4.4gr BE and 7.2-7.8 AA5. Zip is close to AA2 so the load data is 3.8-4.7AA2

 

[AJC1]

Consider if your not downloading or using minimum loads your chance of leading or some other mishap is probable.... the pressure and velocity are going to be insane in 357 but 38 will be easy day...

Following this thread as I’m about to start with125 grain Gallant lead coated in 38 Special. Not in a rifle but 6.5” Roger Blackhawk.
