A friend of mine has a 9.4 Dutch service revolver and since they supprisingly don't stock that any where. We where wondering if anyone had any info on how to reload for it. Like what brass could be formed to make the round and what size bullet one would need, plus the obvious how much of what type of powder. He found somebody that actully makes dies for that caliber.
The caliber is 9.4 Dutch and it is the double action revolver.

I have no idea, but have you looked at Norma and their web sight to see if they have some? Also old western scrounger might be a good sorce, and lastly, get a copy of gun carterages of the world if it was or is made, they will have information on it. And Sierra has a web question and answer sight as well as a phone in area where they can answer your questins. Sierra has been very helpfull for me in provideing information in the past even to the extent of mailing tone is info to me at no cost. They are great there!

Since 303 savage is no longer made check out 220 swift for a basis.
Also double and triple check your guns chamber sizes as it seems from the info in the book there is a bit of variety.
