Someone here had a Canjur for sale, they are a wonderful single set trigger, you might check the adds. Lets see I've got four Remington 700's in the safe and all have factory triggers and been adjusted to 3 to 3.5 pounds.
I don't have any problems adjusting the sear and overtravel, but I've been doing that for a lot of years. A trigger adjusted for those weights that has no overtravel and no creep can feel much lighter than it actually is. A good Remington factory trigger is capable of that.
Two things can happen if you adjust a Remington trigger to light. It will go off when you close the bolt or it will go off when you take the safety off when cocked.
The bounce the butt on the floor test is one you'll want to do and taking the safety off and on when cocked several times and closing the bolt several times, both really hard and soft will tell you if it's set to light.
I'd recommend not going below three pounds with a Remington factory trigger. Of the several hundred I've adjusted over the years I've ran into a few that simply wouldn't adjust and when that happens it's time to consider an aftermarket trigger.
Installing an aftermarket trigger is just a matter of punching out two pins and dissembling the safety to install on the new aftermarket trigger on the older Remingtons. Watch the little ball bearing, it's easy to loose.
Changing out the new Remington trigger is even easier as you can't dissemble the safety and a new aftermarket trigger will come with a safety.
