I am a wood/blued rifle lover as well, but have one stainless/synthetic M700 that I reserve strictly for nasty
weather hunts.
I have a 38-55 Marlin 1893 that was built in 1906. It started life as a 30-30, but erosion and corrosion took it's toll.
Because I liked the platform so much, I had Ron Smith rebore the rifle to 38-55, and I have no intention of ever
getting rid of it.
I am weak when it comes to highly figured walnut [or even maple] and have several rifles that have a fair amount
of classy wood. These are keepers, also.
To the OP......your suggestion of a 270 in a classic rifle is superb, IMHO. Flat shooting, effective, and easy to feed.
