Looking for tips. Will start loading soon for my new Ruger #1. I have bullets and powders on hand for my 9.3 x 62s, just need dies and an accurate way to trim cases. Any advice/pointers appreciated, thanks,namsag.

What I meant to say is ,where do you get a case holder or die to trim this cartridge? I cannot find one.

Using most (any ?) types of trimmers, a 9,3 (.366) pilot is easy to turn down from a .375 pilot. A unmodified 9 Makarov pilot may probably work too. In a pinch and while not as accurate, a std. 9 mm or .38 pilot will do (if you don't crimp your bullets, you won't even feel any difference).

Case holder and die? I use a Lyman trimmer that uses neither. I make pilots.
But actually, I never trim them. They go for many loads without it.

I can trim with a regular forester die..but if one wants to crimp cases I always suggest the more accurate and inexpensive File Trim die from RCBS..It not really a problem either way..

You can get by just fine by using a new factory unfired case to set your trimmer for length, then use a button that's close to a 9.3..I have used a 338 and a 35 button, both are fairly close and I had good results with both. You can also chuck up a button in your drill press and using a file and wet/dry paper cut it down to a perfect fit I suppose.

Thanks for the advice guys I am going to look into your suggestions. Happy shooting.

I offer to modify any trimmer pilot for free. To whatever dimension you want.

I have used the Lyman trimmer, the orange one, for 34 years now. It uses a universal shell holder (pop in the case, turn the handle to lock the cam-lock, trim, reverse the handle, and pop out). The .36 pilot I bought on ebay is, I believe, from RCBS. All works without a hitch.
I recently bought 73 pieces of new, primed Winchester 9.3x74R brass (European, I think) most of which had slight neck nicks. My old Lyman, using the electric drill attachment, trimmed those that needed it in short order. No problema.

Thanks Steve, and dpcd, thank you sir for your kind offer. I have an L. E. Wilson trimmer setup and I found out they can make me a case holder, looks like I will be set.
