About it being worth the extra money; I don't know how much more they're asking for the 40X trigger upgrade...I also couldn't say if it's worth it or not. However, were I getting a 700P I would go for it so long as the price stayed reasonable.
As far as something better, the sky (or more appropriately your checking account) is the limit. :wink: It all depends on how much you want to spend.
Some of our other members here might have some more insight to offer.
The Jewel is the best of the best for a 700. Installed and properly set I charge $245. Most people don't properly set them. They just put in the 2 pins and send it on. If you want to do it yourself it's not too much trouble. Just takes a little time and paitients. I will warn you to be careful. Most good intentions turn out to be bad ideas if you don't do it right.
Don't waste your time with the upgrade unless it's cheap. The triggers are almost exactly the same. You just get a little more adjustment out of them. It will suck when it comes from Remington anyway so why pay for it?
I agree with patriot. The Jewells are very nice, I also like Shilen and Timney which are about half the price of the Jewell. The 40X triggers also have external adjustments (you don't have to pull the barreled action out of the stock to adjust the trigger). But it does depend on how much they are charging.
I've shot the standard from the box Remy, a Jered adjusted (2.5-2.75 lb)Remy, a shilen, and the Jewel. There is no question in my mind - if you can afford the Jewel, that is your ticket to happiness - that is why I have them in both of my current rifles (and will have one in my upcoming 6.5x55 Swede).
The best way I think to go with a 700 Trigger is a Jewell. They work awesome and can be set super light. However they can be a little on the expensive side if you dont wish to spend the money. I myself tweaked all of my 700 triggers myself by taking the action off of the stock and scraping off the crap covering the screws and adjusting the trigger pull screw. I would not recommend this be done to anyone who is not familiar with a 700. 700P's I believe can have a 40X trigger installed for an extra price, but I am not sure on that one.
