currently loading 5.0 grains of w231 under a 125 grain precision hi-tek coated lead bullet. i've also got 147 grain hi-teks and looking for a w231 min/max load.

Please advise if you are inquiring about using those "147grain hi-teks" (9mm ?) bullets in a 357 Magnum application or in a 357 SIG application...?

The 1st is probably not advisable...

I'm not familiar with Hi-Tek bullets, but you might look at Hodgdon data as a place to start. They list a variety of cast and jacketed bullets in your approximate weight range with 231 powder.
 
precision hi-teks are lead cast. i've checked online resources - hodgdon and others - nothing for a lead 146-148 and w231, and lyman's #49.
 
Well, here's your problem. You bought some SOFT swaged COWBOY ACTION bullets made to load to about 700 to 750fps.
38 147 FP
.38 Caliber (.358 diameter)
Cowboy Bullet
Must Use TAPER CRIMP die
Swaged with certified 6/2 lead alloy
Coated with our unique dry-lube formula

So your powder charge is limited to how fast you can go before you smear that soft bullet down the bore. If you are wanting to shoot Cowboy Action, GREAT! 3.5 gr 231 will send the bullet downrange. If you want to load to .357 speeds, sorry 'bout that.

yep, as i originally posted they're a cast lead alloy and slow poke loads are what i'm after and that confirms what i was extrapolating from some the load data i'd seen so far. thanx.
 
Hodgdon lists a 148 grain LHBWC with 3.5 grains of W231 at 869fps. It's a minimum load for 38spcl. You could do 4.0 grains in the 357 mag case with your bullet and back it down till it gets stuck in the barrel. Don't laugh, I've heard SASS guys talk about seeing their bullet in flight.:D
 
yeah, i saw that load on the hodgdon's reloading page, just thought that was a low charge as compared to their 125 grain listing with w231. i've heard back from some of the bullet makers who are using hi-tek coatings and they're saying no problem to reasonably up the powder charge and increase the fps as the hi-tek coating can take it. i'm using 5.0 of w231 for 125 grains, with zero leading or any issues at all, and i'm wondering if that same charge would work well with 147 grains. rather than the smith 60, i'd do the testing in a far more massive ruger 6.5" blackhawk and see how the primer and brass fares after firing.
 
I've loaded coated SWC's from MBC to full on magnum loads for 357mag and 44mag with no leading. Hi-tek coating works.

But........... Unless you specifically ordered a softer (38 Special) bullet, the MBC bullets are 18 brinell hardness. The bullets they sell intended for 38 Special are 12 brinell hardness.

I don't know how much leeway the Hi Tek coating gives you with a softer lead compound bullet like he has bought.
 
i can't remember which outfit i spoke directly with - acme, BBI, or precision - but i was told no problem with their hi-tek coated soft lead alloy handgun bullets going as fast as the typical copper jacketed variety. ymmv.
 
You can't go too bad with a coated lead bullet for plinking and
also getting minimum barrel deposits.

I never pushed a lead bullet in my .357 Mag's unless it was my one, big game bullet.

I kept the lead at low easy to handle loads for all of us to enjoy
while killing rabid paper targets and tin cans.

Enjoy those bullets.

He did mention the softer alloy and I forgot. No idea how they'll hold up at higher FPS.
 
The bullets linked are designed for 9mm pistols. They can be loaded, if one has the experience/understanding of crimping. I would not load these bullets with mid to upper 357 Mag data, even with a crimp rolled into the side (breaking/cutting the coating). There are a few bullet manufacturers that offer coated, .358" revolver bullets, so I would suggest you put these semi-auto bullets on a shelf, and get some bullets with a crimp groove or cannalure.

I have fired Hi-Tek bullets in my 9mms up to 1,200 fps with out problems and coating, both PC and Hi-Tek, work much like a "softer" jacket, allowing higher velocities than nekkid lead...
 
As a note;
in post #3 the picture shows a smooth wall bullet design that is
a typical type bullet used for the 9mm. pistol.

They may work in low velocity 38 special loads..........
but any of the bullets that I load for my .357 Magnum loads, ALL
have a cannelure on them, so I don't run into problems.

You can use smooth walled bullets but they might jump.
 
what 9mm bullets??

these Precision Bullets (the company) .38 caliber, .358 sized, 125 and 147 grain lead alloy hi-teks are listed as "cowboy bullets", which, according to them and that designation means revolvers and lever action rifles. a taper crimp is specified. i've loaded and shot hundreds of these in a variety of brand/model revolvers from smith to ruger, no issues at all with the fired cases or the guns themselves.

38 147 FP - precisionbullets.com
 
SO .... Precision Bullets also sells the same hi-tek slicks in 9mm, 40 and 45, presumably for semi-autos, using a taper crimp, so therefore these would all be dangerous loads that could increase a cartridge OAL and create an unsafe load if not jam the gun. really?
 
231

HP-38 & 231 powders are the same, HP-38 data is easier to find in older re-loading info.; I use the HP-38 data with good results in 38 spc & 357 mag. I only shoot the 357's in my Marlin CB rifle.

w231 and hp38 - i thought that was common knowledge and do the same with listed loads for either.
