Home Forums Hunting & Shooting Gunsmithing Opening up a seater die?

Another option would be to anneal the seater die you want to ream with your chamber reamer.

I've been doing this for about 40 years on band saws, so that they can flex after welding, when going around the bandmill wheels.

Heat the entire die to a dull red and hold the color for about 30 seconds, then SLOWLY pull the torch back, letting the die cool very slowly.
