Customized Marlin 336 Cowboy Barrel Question

[38-72]

I’m building an early Marlin 336 into a long octagon barreled 32-40 “cowboy” style rifle. It will be a lead bullet shooter. Which barrel maker would you all recommend and why?

Jes re-borring
3 groove rifling with .006" groove debth.
Works sooooo good with boolits.

The last time I checked JES wasn't doing anything under 35cal! I WOULD recommend them for a 35-30/30 or 38-55.

You might check with Badger, I had a 26" 38-55 barrel for a Model 94 Winchester that looked awfully good.
