I was just wondering if the Remington 700ml's have unsafe triggers like their center-fires because I'm considering buying one for a smokeless build?
Triggers for the older Remington 700's including the muzzleloaders were suspect for many years. The biggest problem came from a trigger assembly called a 'Walker Trigger'. They can fire when flipping the safety off and also when the bolt is slammed forward.
Both of these incidents occur when the trigger is not adjusted correctly. Or afer a long period of time when wear occurs within the trigger either because of lack of lubrication or wear on the moving parts.
The biggest problem has come when people adjust the trigger themselves and get the Sear Engagement set to fine. Because of this and at this point I believe Remington's policy remains the same if you have adjusted your trigger Remington will not warranty it at all.
This drawing and information sheet does show how to adjust the trigger - but unless you are experianced I would not do it on your own. If you do adjust you own trigger test it completely to make sure the sear does not release the firing pin on its own. This usually happens when the trigger is adjusted to light and the sear adjustment is adjusted to fine to reduce creep. It becomes almost a 'hair trigger'.
The Walker trigger is a good trigger if it adjusted correctly and maintained.
Here is some information.
And Swampman is somewhat correct... the documentary produced about the trigger was for 'sensation'. Most often everything written fails to mention that the trigger can be adjusted to solve the problem, and/or Remington will actually replace trigger if it is truly defective and has not been adjusted by an owner.
