If I am reading this correctly the new "guy" is the second gunsmith and he is the one sending it to Remington???

I first gotta ask why he is going up in weight?

Second is why on earth would a gunsmith need to send a gun back to Remington because of the trigger not going up in weight enough? It could be something as simple as a burr, piece of gritt, etc... Remington triggers are very simple to work on, do a real trigger job on and just make regular adjustments on.
