Didn't do mine, an early seventies 40-XB, because I like the trigger for shooting, I only use it for shooting at targets on a range, and I have had no trouble with it. However, I do believe that there is a problem with the design. I have a tag hanging from the forward sling attachment point which reads
WARNING: This Remington 40-XB rifle uses a trigger
assembly designed for TARGET USE ONLY. Under
certain circumstances, this rifle may discharge when being
loaded or unloaded. It may discharge upon opening or
closing the bolt, upon setting or releasing the safety, or even
upon pulling the trigger. The rifle must always be oriented
with the possibility of UNEXPECTED DISCHARGE in
mind. Constant safe orientation is likely only at a formal target
range. If you don't understand the above, or even just disagree
with it, KEEP YOUR HANDS OFF OF THIS RIFLE.
