Oh, it had about a medium trigger pull from the factory(never measured it).
Incidentally a friend of mine has a Jeep Cherokee for many years that had a 30 caliber hole in the roof from a similar AD in another 700. It was not as repeatable but it would do it - and it was a stock gun.
I will take you at your word, but I find your story very hard to swallow - You sawed up a perfectly good gun rather than simply replacing the action? Even if you had lost confidence in the Remington action, why not just replace it with an aftermarket? and sadly, the evidence of your claim is (like all the others) irretrievable. You are the first person I have ever talked to that had any trouble at all.
I too use a lighter pull than factory - though not too light, as I am in brush country quite a bit to get to where the elk are, and a light trigger in brush is just asking for trouble, just in case I forget to set the safety.
Before I got sick, I went shooting A LOT, to the point of re-barreling both of the Rem 700 7mm mags that I have owned (with actions fully rebuilt at the same time). Even when extremely worn out, I have not found your problem to occur, but if it did, I wouldn't pitch the gun, I would fix the action. And if I could not figger it out, my gunsmith certainly would - that's why all my guns go in annually - not so much because I am not capable, but just to get another set of eyes on the job.
And if Remington's shop didn't fix the problem, I would be pissed off enough to MAKE them fix it right, or I would have it fixed elsewhere and send them a bill for my troubles.
Maybe that is just a difference between you and me, and I get that... but I find your actions to be outside of my normal 'norm' (and those around me too).
