I saw a YouTube of a guy using 5.7x28 brass to make .303 British bullets at .311”. I was thinking that if I got a 5.56 case and cut it off at the right length, heat the whole case to anneal the brass, drive the case through a sizing die at .366”, fill the case with lead from my Lee pot and drive it into a rough pointing die. Would I have cheap (my labour for projects is free to me) bullets for the 9.3x62? Like at most ranges, I have access to lots of 5.56 brass and a pipe cutter to rough trim it to bullet length. The 5.56 brass is nominally .373” at the base and can be sized down to .366” through a Lee .358” sizer opened up.
The YouTuber cut the rims off flush with the extractor groove for a modified boat tail, this might be useful.
I have made 35 Rem brass from .308 Win by driving it right through a .44mag sizer die to reduce the head and web from .473” to .460” so from .373” to .366” shouldn’t be that hard. The 35 Rem brass needs the power of a hydraulic shop press to push it through. The smaller starting diameter and with only .007” difference vs .013” there may be enough leverage in my Rockchucker. The problem is the forming die would need a shop press or bench vise for power.
The pointing die would probably be for a tapered flat nose design to accommodate a bullet ejector pin. Preheating the brass before pouring the pure lead core would be easy, toss them into the pot and pick them out of the lead one at a time before pouring the core.
