Before you ditch a great trigger...
Before you change triggers, work on the trigger already on your gun. Most, if not all, of the 721/722 series had factory equipped adjustable triggers that are as good as any aftermarket trigger I've picked up.
On the factory trigger, the adjustment screws are recessed into the front and rear of the trigger assembly, sandwiched between the steel plates that form the body of the assembly.
Instead of retrofitting a 700 trigger, or shelling out for a new adjustable trigger, I'd tear down the trigger assembly, give it a thorough scrubbing and oiling, then reassemble and try to dial it in to a good weight.
Look for a sticky film on the parts. It's horrifying how many well-meaning folks oil guns with WD40. WD40 is fabulous stuff, but contains detergent. As the oil evaporates off, the detergent remains to form a golden colored film that's as sticky as glue.
The screw on the back of the assembly adjusts travel, and the screw in the front adjusts tension. With a little tweaking, you can get the 721/722 dialed down to a reliable 1.5 pounds.
If you need help with the assembly, email me, and I'll send photos.
One last note, the 721/722 rifles have a reputation for spontaneously firing when the trigger is set under 3 pounds and the gun is switched from Safe to Fire with a live round in the chamber. I've never experienced this personally, but other posters say it has happened to them. Be aware; be safe.
