FWIW...
Own 2 of 'em. The 70s version 25.06 Varminter BDL was a good rifle, shot about an 1/8" three shot group with it once with handloads. Couple years back I turned it into a bench rifle, new stock, etc.
The Sendero 300 WM shortly after they were introduced, not very impressed at all with it. Maybe 200 rounds through it, had to have the headspace corrected. Groups tight enough now, but the finish on the metal is looking the shabbiest of all my rifles.
Design-wise, IMHO, they're long overdue for some serious improvements. The bottom metal is cheap junk, the extractors are weakness that most other makers improve with a reliable Sako-like version, and if one is not careful with reassembly post cleaning, the poorly designed magazine can bind between the floorplate and the action. I haven't picked a new one off a rack in years that impressed me in the slightest with fit and finish.
Just read an article in latest issue of Shooting Times, where they tested three each of the Browning X-bolt, CZ 550 American, Ruger 77 Hawkeye, Savage 114 American, Win. Model 70 Sporter and Rem. 700 BDL.
To my surprise, the Winchester topped the bunch of 'em overall.
The Savage shot the tightest groups...while the Rems came in last for groups. Also notable, the Rems averaged 4.9 oz. trigger pull, with 16 oz. variation, worst of the bunch. To me, that's just plain inexcusable these days!
I've had opportunity to handle and shoot a Tikka T3, and a Sako A7. Frankly, the 700s don't come close.
Again, FWIW.
