I wonder if anyone has had any experience of forming 8 x 57 brass from 7x57 brass?
I have been offered a load of once fired 7x57 brass that I could reform to 8 x 57 for my rifle. Is it a matter of just running it into a 8x57 FL sizer or are there any intermediate steps?
The shoulder dimensions on the 7x57 are certainly different but I dont know if the 8x57 die will push them to correct shape.
I did wonder about running the cases over the expander ball in an old .308 sizer to make the neck diameter increase in two, smaller steps.
Any thoughts / advice?
