I found some forming dies for my 1903 6.5x54MS. They are marked step 1 & step 2. How do I use them and what is the parent case? I believe they are Lee brand.
Please don't take this for gospel, but I did a little research and found a comment that 6.5x54MS brass can be formed from 8x57 brass. I have never tried this nor have talked to anyone who has done it. I'm just passing what information I found along to you. I'm also assuming that RCBS made your reforming dies, since I don't believe Lee ever made any types of reforming dies. Good luck
Mick, not sure if this has much relevance to the use of your dies, 20thou is a big swage down in head size & I don't even know if it would be possible. Norma lists the 6.5 Carcano case which should resize OK, they may be a couple of thou undersize & it would pay to neck them up to a bigger size (maybe 8mm) & then neck them down to 6.5 again as the Carcano cases are shorter to the shoulder than the MS cases & would have excessive head space. Just neck them enough to be a tight fit in your chamber before fireforming. If you know somwone who can do some machining for not a lot, an alternative might be to turn the rim off 303 cases, turning a new extractor groove at the same time, & then use your form dies. 303 cases are lightly big at the base, .460" as against .452 for the MS case but this is in a range which should reform & some brands may even be closer than that. Being in Aus this might be a simpler route to take but I'd go with Carcano cases if I could get them. A good website for dimensions is http://stevespages.com/page8d.htm Not me though.
