To the OP, Ruger does (did) not make a varmint (1-V) in .270 as far as I know.
The .270 has been chambered in the 1-B (26" medium contour barrel, quarter rib, no sights), the 1-A (22" barrel, quarter rib, sights, Alex Henry forstock), the 1-AB (same as 1-A except no sights [most, apparently some exceptions], beavertail forestock, some might have a 24" barrel), the 1-RSI (20" barrel, sights, full length forstock).
The 1-V (26" heavy barrel, no sights, scope blocks instead of quarter rib) has been made in 7 mag and 300 mag, and possibly .280, but apparently not .270.
There have been Stainless Laminate versions of most of the above, except for the RSI and AB (can always be wrong when discussing Rugers).
