Reloading 380acp with Wolf SPMP????

[WLE]

I now have plenty of SPMP for my 357 mag., however I still can't seem to get any SPP, and all my sources still have them on back order. I would like some feedback from those who have knowledge or actually reloaded 380 acp with Wolf mag. Primers and if so, what loads would you suggest with 95 gr. LRN. I was concerned even if I loaded at the starting loads, that the pressure would be excessive. I tried searching for this information but I can not seam to find any sources for substituting primers. I believe that Wolf primes are not as potent as CCI. If I make the powder charges 10% lower then the starting load, will I still have excessive pressures??? Example: 3.0 gr. 0f 231 less 10 % Should be 2.7 grains to start???. I really don’t feel comfortable and don’t want to be shooting in the dark.
Domestic primer companies, include CCI, Federal, Rem., Win., How reliable are the Russian Primers? Are they just as reliable as Domestic? Where can I find technical data loads substituting primers since we are now into a new era and must now use some Kentucky Windage to continue this great sport?

Thanks Guys,

Bill

For what its worth, I know a guy who uses Wolf primers and loves them. He also only uses the SPMP exclusively in all his SP loads. This question just recently went threw here, here is the link for it http://www.thehighroad.org/showthread.php?t=474128 . The jist is that it really doesn't make that much of a difference, and if it does it is only in max loads. Wolf primers are fine BTW.

Thanks jibbs, I checked out the link, however, I was not sure what the pressures would be with a smaller cal. and less of a powder charge.

I am by no means an expert and that the smaller cases there might be something going on there. If you have access to a chrono, you could just start and work up your loads and see how much faster the bullets are traveling, larger increases in fps may have a correlation in increased pressure. I doubt you would see any significant increase in velocity (+-20 fps) You can look at the casing itself for signs of increases pressure such as bulging or flattened primers.

I am not familiar with .380acp, but in a .40S&W there is little/no noticable difference and thats a high pressure cartridge (which is shot in my case in a unsupported Glock barrel). Don't really notice a in increased pressure. Hope this helps and hopefully someone more knowledgeable then me can chime in as well.

I was not sure what the pressures would be with a smaller cal. and less of a powder charge.

The fast burning powder used in small doses in the .380 ACP only has so much energy / pressure it can produce.

I'd venture an opinion that the only difference in pressure you could see or measure would be the difference in the primer charge between a standard & magnum primer.

In other words, very little to none.

I think the place you would see a possible problem would be a big load of slow burning powder in a large capacity Magnum revolver case.

Lighting more of it sooner could increase pressure.

But there is so little fast burning powder used in a .380 ACP that it all goes bang pretty much at the same time anyway, regardless of what you light it with.

Only if you are already at a MAX load, reduce it 5% - 10% and work back up, just as you should do anytime you change components.

I'm in a smilar situation but with Fed mag primers - no std sp's around here.
I loaded 24 cast .380acp slug loads with the 'start' charge of Red Dot and they did fine, in fact I'm going to bump up the powder a bit but still short of 'max'.
