Finally got around to changing out the trigger spring kit. I purchased a few of them for my old Model 70's and grabbed a couple for the MOA trigger's as well. The hunting springs for the old style Model 70's are excellent. They allow me to safely adjust the triggers to right around 2.5 lb's which is where I like my triggers.

My Model 70 300WSM is a newer FN gun with the MOA trigger. Very nice trigger, no creep or overtravel, but the pull weight could not be adjusted to below about 3.5 lb's. While alot of guys prefer the extra weight, I don't. It wasn't bad at all, just heavier when your used to about 2.5. Well, you do have to punch a few pins out that hold the trigger in the receiver and one pin outta the trigger assembly to get the actuator out, the hardest part was finagling the little spring back into place, but once I figured out the way to get it back in, it was pretty quick, probably took me about 30 minutes.

Once I got it back together, I adjusted it about as low as it would go at 2.75lb's which was within the specs of the spring at 2.5-3lb's so I am pretty happy. The trigger actually feels lighter than it actually is, so I am looking forward to testing it back out on the range, as it feels like a brand new trigger.

Here are some links to the kits and instructions.

I say give it a whirl before you spend big money on another trigger, as it is about 5-6.00 you'll be out, and if you don't like it, you won't feel sick to your stomach spending too much on the small tune up.
 
Looks good, Scotty. I do have several of the newer MOA springs. They haven't given me much trouble, however. Nevertheless, being an inveterate tinkerer... Good intel.
 
I knew you'd be pleased, Scotty. The spring made a world of difference on my 70 Classic w/MOA.
 
Pat, it's worth a shot and also, order a couple Pre 64 style trigger springs as well. I've pretty much been able to adjust the entire fleet of Model 70's to 2-3lbs now with 0 take up or over travel. A little light stoning on a few have gotten to 0 creep. Very happy with the springs. Still like the Pre 64 trigger more, but the MOA trigger is much nicer being in the sub 3lb area.
 
Spring kits are the way to go. I put two in my USFA SAA .45 Colts, it made all the difference in trigger pull weight and helped accuracy.
 
Nice going Soctty, I also changed mine on my new to me Mod 70 SS FWT on Saturday as well. Really easy to do with two punches and a really small screwdriver to finagle the spring out/in. It came out around the same as yours did with the adjustment screw backed out about 3/4 of the way. The trigger breaks really well and I'm happy with the way it came out. Very good $6 spent. The hardest part of the job was getting the magazine box back into place after it popped out of the action. It fits in there pretty tight and I had to tap it in with a small rubber mallet, so hopefully it's not binding after I tourqued the actions screws. Looks and feels just right, but didn't have a chance to load or shoot her yet. This is my third Mod 70 and the first one that I put a lighter sping in the trigger. I have two more and am set to do my EW and my Dad's 270 WSM FWT LTD Ed this coming weekend.
