Marco, I think you will find that most armies tried to use a fairly fast-burning powder: less weight to transport, less dollars, pounds, lira, marks to spend, being that it all costs about the same to produce.

I have a Carcano Model 41 and it is just wonderfully accurate. I am using the cheap (bulk-pack) Remington 140-grain flat-base pointed bullet in my rifle. This is actually a .264" diameter bullet, but the rifle likes it, so that is what I feed it; the correct Carcano bullet should be about .268", so my bullets are 1/10 of a millimetre too small. All I can say is that the rifle likes them.... and the rifle is the boss. I seat my bullets as closely as I can to the length of a factory Carcano round; I think this is important because these rifles all had very long throats.

On this side of the Atlantic, the only maker to offer a correct Carcano bullet is Hornady. You are in Europe, though, and your neighbours in Serbia make proper Carcano bullets at the Prvi Partizan factory in Uzice.

I do not know the Vihtavuori powders at all. We don't see them very much here and, when we do, they are very expensive. For a very mild load, I have used 28 grains of IMR-4198.

I hope this is a bit of help.
