Help - .38 SPL 158 GR Lead Cast FP/Truncated Cone with VIHT N320

[SukhaSD]

I’ve just started reloading and have a few questions:

Firstly being does anyone have load data for Viht N320, in .38 SPL 158GR Lead Cast / Truncated Cone?

I have found it incredibly hard to find data for this bullet/powder combination.

Currently I have the below:
.38 SPL Case
158 GR Lead Cast Flat Point / Truncated Cone
4.2 GR Vihtavuori N320

I’ve measured the COA length for the 8 rounds that I have loaded, and they range from 1.4475 inches to 1.4425.

I’m fine with pulling these bullets, whether I can utilise the powder and bullet again or not.
Just wanted to make sure before actually firing them, and certainly didn’t want to load anymore than I already have.

Any help would be much appreciated.

Thanks

Looks ok. Just lightly crimp in the crinp groove, as it looks like you did. Your 2/10 gr below starting load listed. Should be fine.

Make sure the length is not to long for the cylinder.

I've had good loads with a similar bullet in 38 spl with 320 with 3.5-4.5 gr 320

Welcome to the forum!

The Vihtavuori app is free to download. I find it really useful when I’m at the store looking at available powder on the shelf. I can quickly check if it is useful for anything I want to reload.

Should be an excellent powder for that load.
