I've owned & shot many 700s over the past 50 years. Re-working triggers is simple enough, and very safe when done correctly.
A few years ago, I sent one out to a well-reputed 'smith in Glendora, Ca., for a set-back and , as I no longer have the machinery. While there, he tuned the trigger to an excellent feeling and consistent 2.5 lb. pull. After the season, I let the rifle wait out the winter in the safe. Three months later, it was time to put her back to work... When the bolt was closed and safety "on", it consistently discharged upon release of the safety. Sparkling clean, dry or lubed. Every time. The 'smith had sealed the adjustment screws with such a glob of JB Weld that I had to replace the assembly.
NOT a problem with Remington's trigger, just an example of improper handling. I am fond of the old Remington triggers, and trust them as much as any others.
