I use the 8mm Karibiner, still available from Mid South IIRC. Shoots great in anything with a decent barrel so far. But if you are shooting a 7.65 Argie you want .312-.315, not .323-.325. Maybe I'm confused on what you're asking.
That 323470 is a great Loverin design for most 8mm cartridges. I use it exclusively for both my 1888/05 German Commission Rifle and my .32 Winchester Special Winchester when I size it at .323" for their .321" bores. For my 8x57 and 8mm-06 rifles I size them as cast at around .325" with my alloy blend.Yea sorry for confusion. I have many 30/31 cal molds. I have one fat louverne that drops .318/319 but nothing yet in 325 range.
I just committed to a mold IDEAL #323470 from S mac

I was in on the original 8mm Karabiner buy. It was designedf the worn throat military rifles that were plentiful and cheap in those days. Use it in a barrel with an unworn throat and you have to seat the bullet way deep in the case.
Ben - if you are a big 8mm fan, you need to visit Larrys! Bunch of Mauser sporters, complete with d&t receivers, aftermarket bbls, sporter stocks AND VERY nice double set triggers. And $300-$370! Kicker - no recoil pad! And they will need one!
Any of you other yahoos interested in such an animal, I would be happy to help pick a nice one out and work with the local LGS for transfer. I almost had to duct tape my hands behind my back after throwing my wallet in the parking lot to keep from taking one home! I do NOT need an 8MM! I DO NOT! (I keep telling myself! - espc after buying 2 357 revolvers today... just sayin'!)
I was in there 7 days ago, yes, some look nice, others....not so.
