Re: Anyone have .418 parallel reamer
19mm silver steel bar
6.5mm, 10mm and 10.5mm reamer
Mike Neumann's tip for polishing. You can use a wooden dowel turned to size, I had this aluminium tube lying around.
800 grit silicon carbide paper .
Push rod on left is for 377 lyman die. Sizing in two steps, cast to .421, then .421 to final.
Holder is made from a bolt, drilled out and turned to fit the lyman lube sizer dies.
Sized to just over .416, closer to .417 . For the .416 Ruger, the bullet size affects chambering, it doesn't like oversize bullets. The .421 lead bullet when seated will not chamber, even after crimping, etc. This 416-7 chambers fine.
