Winchester Model 70. Probably the best hunting-rifle trigger, period. What sets it apart is its extreme simplicity and ruggedness. Properly set up, it has a wonderful pull, and almost nothing can keep it from working properly. If you don't like your Model 70 trigger, don't replace it; have it tuned.
Remington Model 700. Properly adjusted, it offers the best pull of any factory trigger. However, it is susceptible to accumulated grease, rust, and idiots who insist on tampering with it.
Weatherby Mark V. Weatherby uses a high-tech machine called the Trigger-Scan system to adjust their triggers at the factory, and their pulls are good right out of the box. The system not only adjusts but also records how many thousandths of an inch of engagement, and how many pounds of pull, go into each trigger.
Browning A-Bolt. Like the Weatherby triggers, the ones I've tried have been fine, unless you're really fussy. But if you are fussy, a slicked-up A-Bolt trigger is a sensual delight.
Savage 110, 111, 116. Savage rifles can shoot with anything at any price, but triggers have long been their weak spot. A gunsmith can lighten a Savage trigger, but the basic pull is still nothing to write home about.
Ruger Model 77. The ones I've tried have been way too heavy, but they can be cleaned up.
Marlin 336 and Savage Model 99. These are the only lever actions I know of whose triggers can be slicked up. A well-tuned Model 99 trigger is particularly nice.
