My 20” Whelen was a .270 that I bought used and sent to be rebored by JES. I put it into a B&C synthetic stock, replaced the firing pin and spring, added a Trigger Tech Primary and had the bolt spiral fluted and changed the bolt knob. It’s designed for sub 200 yard work and it’ll shoot 250-280gr cup & core or 225 monos.
My .338wm is setup for 200-225gr while I use the Whelen for the heavy’s. I’m sending two rifles to JES in the coming months one will become a 24” .338wm and the 1953 model 70 will become a 24” Whelen.
It’s been my experience that the “medium” bores are not finicky and typically shoot well.
