Free: Contests & Raffles.
So whats next ? Ive never seen a reamer used. Put barrel in lathe and reamer in stock end ? Or just send to your fav smith ?

Looks like you got a lil freebore there for the longer bullets. Waiting Sucks!
This cartrage is going to be sweet. Have you decided how you'll do your brass?
That would be sweet with the faster twist. Might even work with the slower 1/9.
Who was the reamer maker? With the screw for retaining the pilot I would say JGS or PTG.If the flutes extend all the way to the end (like the PTG) and the guy chambering uses a pumped coolant system, below is a trick to increase coolant flow. The more flow, the cooler the reamer cuts and the smoother a chamber you wind up with. Also allows running the reamer at the proper lathe RPM instead of down in the slow speed range. I cut small chambers like 223 at 470 RPM and larger chambers 30-06 size and above at 370 RPM. Ya cannot run this fast without a lot of coolant flow.With the pilot bushing removed and the screw tight, I file notches in the screw head aligned with the reamer flutes. This is why I like PTG reamers, the flutes go all the way to the tip.This reamer is for 458 Lott.
