Gunsmithing Remington 700 Trigger Safe Function Check

[rideHPD]

This is probably going to result in countless "if you have to ask, you shouldn't be doing it" posts but that is not what I'm after. I know how to adjust the trigger, and how to function check the trigger by making sure that the trigger is consistently reset by spring pressure so that the trigger always returns so that the firing pin can't drop from the safety being released or the bolt being closed, that it is not too light or the sear engagement is not too short by slamming the bolt closed, etc. My question lies in the later part. I always drop-test my rifles by grabbing the rifle in the foregrip area and hitting the butt against the ground to ensure that the gun would not fire if dropped a short distance. Does anyone else do something similar? I have a new timney that magically became much heavier than it was when installed, and in the venture of trying to see if I can tune it down I can not get it to pass this aspect of a safety check at a desirable pull weight (I'll guess it's at 8lbs min to be safe) I'm going to send it back to timney because the mysterious pull weight change shouldn't happen, but I'd like to see if I'm just asking for too much from the rifle. Simple physics inclines me to think that such a light trigger will naturally fire under this condition from the force of the hit.

Re: Remington 700 Trigger Safe Function Check

I have several old model 700 triggers that easily pass a drop test with a very, very light pull weight. They've been stoned and re-sprung. I beat the shit out of my rifles when I check trigger/safety function.

I suspect your trigger return spring may be binding in the housing. I would suggest seeking Timney's advice.
