Any 380ACP reloaders here ???

[Raiderh20boy]

I have a case of Montana Gold 95gn JHP that I?d like to load with VV N320 for a SIG 238. Any experience with this combination?
Thanks

I reload for P232s and a Beretta 85. I don't have that powder though.

If you are using a progressive go slow and easy. 9mm rattles powder out and 380 is worse.

Thanks for the reply! I use a Dillon 650 and have it running very smooth. Haven?t had hardly any loose powder so far when I was using xtremebullets 100gn RNFPwith 3.3-4 of WIN 231 or HP38.
I just wanted to try the VV320 with Montana Gold 95gn JHP since I got 4k for a GREAT PRICE 😁

I did not have VV N320. When I load .380ACP I used either Titegroup or CFE-Pistol, because:
- I reload all pistol ammos with Titegroup. Easy for me.
- .380ACP is the ammo that uses the least powder of all of my center fire ammos, I use the slowest power for easy metering. I had a choice of 2.3 gr of Titegroup or 3.0 gr of CFE-Pistol, the 3.0 gr CFE-Pistol is easier meter than 2.3 gr. The slowest power I had on hand is CFE-Pistol.

It's not tested data so proceed with the usual load development methods but this is what Quickload has to say:

Cartridge          : .380 Auto (9mm Kurz)
Bullet             : .355, 95gr plated bullet 0.45" long
Useable Case Capaci: 6.969 grain H2O = 0.452 cm?
Cartridge O.A.L. L6: 0.950 inch = 24.13 mm
Barrel Length      : 3.0 inch = 76.2 mm
Powder             : Vihtavuori N320

THANKS AR15 !!
That gives me a great starting point !!
REALLY APPRECIATE IT !!!!!!
I’ve seen a lot of print outs here using Quickload.
Is that a program /APP available ??
Thanks again

Quickload is a computer program that does a prediction of the powder burn.
The prediction is only as good as your input data so it's NOT safe to use the predictions like you would actual tested load data from manuals.

You can fine tune the quickload computer model using your own chronograph data and eventually get your computer model very close to reality, but until you do that, you can't really use the data reliably.
So as usual, start low and work up your load.

Lucky!! Where did you find that Montana Gold 95gn JHP?
Montana Gold seems to have all but given up at this point.

If you ever decide you can't finish all 4K and want to sell some let me know ; ) I'll gladly help lighten your load.

That being said I use 3.5gr of VVN320 out of a Glock 42. Very soft shooting and I am very satisfied with the accuracy.

N320 is not what I would use for 380. I use N310 for 90gr jph and 100gr fmj.
I am in the 2.7-2.9gr range on those bullet weights. I load for two P238s and function and accuracy are superb.

Another great powder for 380 is W231.

[bigbully]

I don't have experience with that powder, but I load Precision Delta 95 grain for a P238 using Win231. Still fine tuning my load though. Didn't like the lower loads so will try some more 3.2 - 3.6 grain loads. Didn't make enough the first time around.
