Although I haven't owned either the Sako or the Weatherby, here's a vote for the Browning A-Bolt.

I've got the Composite Stalker in .300WSM w/BOSS. Wanted the SS Stalker but it wasn't out two years ago in .300WSM and with a BOSS. If you go with an A-Bolt, my advice would be to get the BOSS option. It really works... for instance, I've shot a single ragged hole 3-shot group at 100 yd that measured only .22" extreme center-to-center... and I'm no Bob the Nailer... lol... even though I fancy myself one at times. <smiling>

Oh... even though you haven't asked... I can also recommend a Burris Fullfield II 3x9 scope with Ballistic Plex reticle. It's one helluva scope for under $200. Bright field of view... and with a range-finding type feature. I compared a Leupold Vari-X III directly to the Burris... and the Burris came out ahead.
