Are you asking which brand of reamer?
Bolt action. Using as a trainer for PRS positional practice. 2.455 is current COAL with a .020 jump and 75g ELD..080-.090 is what you would want. Mine is a .080 and I run them about .010 in the lands. I do crunch a little powder when seating bullets but its not much. Also these will be seated longer than any factory 700 mag box will allow so you need to make some modifications. If you are running an AR then yes go with an off the shelf reamer with shorter freebore because they wont fit in the mag if you load them long.
