Reaming after pre-boring

[Dusty Stevens]

Can someone confirm what I think I remember reading.

I think I read where Chad at LRI said he reams a 308 size chamber with a finish reamer in under 2 minutes.

I bet he could do it way faster having ran cnc machines in production a lot. I bet with a big enough spindle motor i could do it in less than 5sec taking it easy….. doesnt mean its good for the reamer or the end product.

Carbide, CNC and doing production work...yes. Basement shop doing it manually for match winning BR barrels, no thank you.
