Jim: The reloading data for the 7.5x55 is in about every reloading book. If not in yours, use .308 Winchester data as a basis. The reloading data available is generally for the M-1911 rifle, an earlier version of the K-31. It's a fine rifle and a fine cartridge. I have several Sweiss straight pulls and enjoy reloading for them.
I hope you didn't spend a fortune for brass. 7.5x55 is easily made from .284 Winchester by simply expanding the neck to 30 caliber. If you ordered Lee 7.5x55 dies you can order one of their "X-pander" decapping rods that has a tapered expander that will do the job in a single pass (an additional $4.00). If not Lee dies, tell me the brand and the thread pitch of your decapping rod and I'll make you one. (Should you be so inclined as to NOT buy commercial Swiss brass)
I have been reloading for the Swiss since '81. If I can be of any help, drop me a line. ~Andy

Thanks for the info Ammoe, I bought some Hornady brass from a guy in Tx for $25 & I am waiting on the Lee dies & my rifle. I checked on the 284 brass & the head is the same as 308 & 30/06, if I need to can I make it from any of the 4000 cases of 308 I have? All I use that stuff for is forming into 250 Sav & 243 (I know I'm cheap lol) I've got a Win 88 in 308 but I put the commercial brass through it.

Jim: I hate to pee on your rose garden but you can't make 7.5x55 safely from .308, 30-06, or the like. The rim of the 308 / 30-06 is the same as the .284 but the head is .030" smaller. The .284 is .500" at the head which makes it ideal for resizing to the Swiss' .491 head. I guess you could make the cases from 30-06 but they wouldn't be too satisfactory and would have to be light loaded, to say the least. The 308 is about one-eight inch short of Swiss length before you ever got to fire-forming, which would make it shorter yet, so you'd have to deal with that, too. To each his own, but the .284 brass seems like the way to go from where I sit. I do have 40 pcs of Interarms/Norma once fired brass around here. If I find it you're welcome to it. ~Andy

Thanks for the info on the brass, I was looking at the rim sizes & the extractor groove size. Oh well hopefully the brass will beat the rifle here but not sure since according to the ups tracker my toy should be here sometime on friday. When it gets here I'll leave a post on what kind of shape it's in, I'm getting it from AIM & have never dealt with them before. talk to ya later
