I did what you did only with an older push feed action--I had a 24" featherweight contour barrel (Shilen match grade chromemolly) chambered for the 275 (7x57) but I had it long throated so I could seat 140-150 grain bulets way out of the case. I get speeds in the 2980fps range with 140 grain bullets--sub moa accuracy. It is housed in a winchester featherweight walnut stock--some day I will replace it with a really fine stick of walnut.
It is reaonably light weight, looks good and shoots well. I have used it on muley's, whitetail, yotes and moose. It may yet come elk hunting with me.
My other choice in a similar rifle is a 35 whelen--24" barrel--if I was doing it again I would stay with 24" barrel but would get it in a lighter contour.
Good luck with solving your dilemma.
