here my problem i have around 2000 rnds of 7,5 mm ball made by privi partizan,now i have a doubt is that cartbridge a 7,5mm french or a 7,5 mm swiss.any idea how to find.the bullet is 140 grs no other marking on the box except 7,5 mm ball.any help appreciate.thanks
 
I am not quite sure what your question is; if you are trying to confirm the identity of the cartridge then I would suggest referring to Cartridges of the World and comparing dimensions in there with those of your cartridges. Use a micrometer to measure them.

I'm guessing it's 7.5mm French. Privi loads it with a 139 grain bullet. They load the Swiss with a 174 grain bullet. The French brass is 54mm long. The Swiss 55mm.
 
Top - 7.5x54 French made by FNM
Bottom- 7.5x55 Swiss, also by FNM.

It seems the FNM used the same powder charge for both.
Accuracy with the FNM Swiss was not that great.

Note also how the bullet is seated much deeper in the Swiss for the K31's tight throat.

My thanks to Eric (Parashooter) for his photo.

why didnt NATO adopt one of these already-made cartridges? 7.5 french must also be very accurate judging at how similar they are.

Because the US (who was, and is largely now, footing the bill for NATO) wanted no less than a .30-calibre rifle, and they were going to be damned if one of their soldiers was going to kill a commie with anything less than a .30 cal. He who pays the bill makes the rules.

7.5x54 French: First used in 1929 in 07/15 light machine gun
7.5x55 Swiss : Dates back to 1911 and was derived from 1890 7.5x 53.5 round.
7.62 Nato : From American Cal. .30 1956 T65E3 round

I guess the US figured out it wouldn't have to pay royalties out after so long a wait. :D
 
Your ammo is 7.5 French, but is it Berdan or Boxer primed? You can make brass for the 7.5 French by running a 6.5 x 55 case through the 6.5 full length sizing dies, use .308 bullets and loading data for .308.

Not really necessary. New, boxer primed brass is available for about $45/100.

Dont use 308 data when using fired FNM/Indep brass as there are stories of case seperation and other issues. I have some really good recipes for 7.5 french and I use the expander ball 6.5 to 7.5 in my RCBS 7.5 Fr dies if I need brass. I have so much that when I started to reload 6.5 I decided to colour the base of all my expanded cases with a permanent marker!
If you need a cracking load pm me. By the way I use the same bullet as 146gn Fmj Nato 7.62 as the old frenchie is a flat base & I have used up all the pulled ones now!
