Anyone ever use JES

[fish4food]

I’ve wanted a 338 Federal for a long time.

I recently got a barreled action with a 6.5 Creed I was thinking of rebarreling.

But I’ve also read about folks using JES to rechamber and rebore a barreled action.

Anyone ever do this?

I have two Marlin 336’s that were rebored by JES. No complaints both are pretty accurate for a levergun.
