Ignoring what I may have said earlier, pro or con, I think it will do well ... int he Swiss Provinces where a 10.3mm calibre is required by law. Instead of some ancient BP designed round, hunters will be able to purchase a round with better ballistics. Lighter bullets for chamois and deer and the like.

Plus useful for hunting large and dangerous game in Africa, driven game in Europe etc.

Edited: Igorrock posted in between me opening the thread and posting. I see he said similar things re the Swiss.

But why do we ponder this cartridge?

This is a discussion forum and that is what is done on a discussion forum. Personally I am interested in this cartridge and its ballistics. And how well it might work.
