Formulas for Plated bullets in 380 . . . ?

Prof Young · May 28, 2018, 08:56 PM

Loaders:
So I'm having trouble finding formulas for berry's plated in 380 - 100 gr. Nothing specific in my Lee book or my Lyman book. Handloads.com not coming through either. I've read you can use the lead formulas for plated but can't find those either. Usually I "adjust" the FMJ formulas and seem to be doing okay so far.

Suggestions welcome.

Life is good.

What I've used to date for a 100gr RN.

Hodgdon HP-38, 2.9 and 3.0gr @ 0.960" OAL, Function was good accuracy was so-so.
AA#5, 4.2 to 4.5gr., max is 5.0gr @ 0.960" OAL, Again function was good and accuracy was better.
Ramshot Silhouette, 3.7gr to 4.2gr,. max is 4.4grgr,. This was the best load in my gun.

Western lists all sorts of load data for 100gr plated bullets. Go look at it.

"You can use any published data as long as it is the same weight (FMJ, Lead, Plated, etc.)
-Standard Plate Bullets max velocity- 1,250 fps."

No need to over think this. It is not nearly as complicated or precise as some people seem to want.

3.1 grains Bullseye, Winchester primers, 100 grain Berry plated hollow base bullets .980 O.A.L.

I back down a bit from jacketed data, if I can't find data for plated bullets.
For .380 and Berry's bullets...

I run: 100 gr HBRN, 0.970" COAL, 3.9 gr Unique.
But, of course, start low and work up.

That load was developed with published data, and in a Taurus PT-138. Subsequent .380s have complained that it's a very hot load. ...Still under published max (4.1 gr), but perceived as very hot by the shooters, cycling the pistols as though it's a bit too peppy, and crossing a chronograph faster than normal.

I'm not sure why I ended up loading with Unique. I distinctly remember a trial with Red Dot performing better and being more accurate...

I don't own a .380 auto, but, found this in the Hornady #8 book: This with a 100gr RN-FMJ: They're best test powder was Win231. Start load: 2.6gr. Max load: 3.5gr.
They list other powders, but, they preferred 231. Vague, I know. But...

I have loaded about 2,000 Rainier plated 100 gr. round nose in .380.
My first were a few with Bullseys and they were OK but dirty.

After that I tried Win 231 with 2.9 gr. and eventually increased up to 3.1 as my happy load.
Most were fired in Bersa Thunder 380 and they shot well. Recently have shot about 75 - 100 rounds in a S&W Bodyguard .380 which also worked well. However I have not increased powder in search of a sweet spot as I was happy with the 3.1 gr. for my casual plinking pleasure.
3.1 gr. is very comfortable to shoot & both guns function well. The new Bodyguard had a few malfunctions at first but after break in seems to shoot them OK.

Marco Califo you have convinced me. You are exactly correct.

I'm at the bench right now loading 9mm Plated 115gr bullets. So I guess there is no need to mark the labels as to which bullets these are. Just that they are 115gr.. Material, size, shape and bullet length make absolutely no difference. I mean as long as they are all the same weight Right! No reason to over think this.

David R · June 15, 2018, 07:20 AM

Loaded quite a few.

Tried the 231, but got less velocity than the book said.

Went to Unique. Load 3.8 for practice and 4.0 for something hotter than factory. Been up to 4.1 for 950 fps. This is where I stopped. Could go to 4.2 according to the book, but not according to my gun.\
Can't tell the difference between hollow base and solid base.

Between me and the girl, we shoot about 500 a year.

Factory loads crony about 850.
We have an LCP, a Kimber Micro and Sig P238.
I seem to find a lot of brass at the range. Its the only caliber I do not sort.

Enjoy

You might want to actually look at the the powder maker websites instead of outdated-beofre-it's-printed manuals, They keep things up to date on a regular basis.

Marco, thanks for posting this and the link. I have had a dickens of a time getting info from Alliant for shooting plated bullets. This is most helpful.

Marco Califo · June 15, 2018, 09:28 PM

I looked at Raniers online a few days ago, and it said the same thing. I have a big box of Ranier 115 gr RN. So, yes, I know what I will load them with. I have some odd 1/2 lb or half tin of some discontinued powders, that will get used up in medium 9mm loads. But, I wold not mix RN and flat point of the same weight, even with the same powder charge. They might behave differently. The max published velocites are with Blue Dot.

Marco Califo · June 15, 2018, 09:42 PM

FITASC, actually I truly appreciate the old pamphlets, especially the ones with data no longer published. Alliant likes to push their newest powders on-line, today Sports Pistol loads predominate their online data, and they are not max FPS by a couple hundred.. The old data for Red Dot, Green Dot and Herco are still valid, and they will email them to you if you ask
There are places with free downloads of the old pamphlets and even manuals.
