jmckinley,
I like the old Remington actions. Got 721's, 722's and even 2 725's in the safe. A few are in different calibers than when they left the factory. The .35 Whelen I am building is based on a Rem. M721 .270 that I got from a friend. Stuck a 25 Shilen Match Grade barrel on it, added a Royal Arms classic magnum walnut stock blank, a Timney trigger and a Sako extractor. At 9 1/2 lbs. complete with scope she is a dream to shoot(sorry no brake for me).
Just a quick note about the muzzle brake idea - a C&H Research mercury recoil reducer will make the felt recoil of a .270 more like that of a mild .243. Anyway I like the older 721 actions and buy everyone I can find. They make great actions for custom jobs. Lawdog
