I read on another forum where a guy was saving money on Weatherby brass by running .25-06 brass into his .240 Weatherby sizing die. Since the '06 case body is slightly larger than the Weatherby, he actually was forming a faux belt on the .25-06 brass. The rim sizes of the two cartridges are identical. The shoulders are close. In my view, this thing just might work and save a few coins to boot.
Has anyone else tried this, and do you do it routinely? I worry about the concentricity of the formed cases; are they straight? Is case life acceptable? What about case separation issues just forward of the web? And most importantly, does the re-formed brass shoot as accurately as the proper-headstamped stuff?
No I have not done it.
But I have read (wish I could name the source, so you could check it) that it is easy to form 240 Wby from 30-06. 25-06 would be a much better place to start.
I can not name a single reason not to use 25-06 to make your cases. I'd love to hear why not from a knowledgeable reloader/wildcatter.
Use lots of lube when forming!
