I want to the lower the trigger on my M70 trigger (old style) I tried the adjustment nuts but the pull still needs to be lower for my liking.
Has anyone tried Ernie the gunsmith's trigger springs or the MCarbo ones?
The Mcarbo removes the two adjustment nuts but that leaves NO pull weight adjustment after that.
Also I do not want to cut my original trigger spring.

Thanx!

The first thing I do is to remove the spring altogether and see what the trigger pull is. You should be able to get it to cock and hold, with no spring, by pointing the muzzle at the floor. Pull should be less than a pound. I have a box full of springs and will substitute with whatever it takes.
If you want, you can remove the locknut, leaving just one nut for adjustment, and depend on Loctite to hold it in place once you have adjusted to the weight you want using the original spring. Regards, Bill

Ive used Earnie's springs and it did lower it but dont know how much. Im not to picky as long as it feels good and is like my others. Course I'm a slapper and not a squeezer when hunting so doesn't really matter much.

This is a heavy barreled varmint rifle. The original trigger was reduced to 2 3/4# but I would like it lighter.

Bill----I backed off on the nuts more but it wouldn't cock.

If you can back off on the nuts enough that it won't cock, you don't need to change the spring. You do need to see if it will cock with the gun pointed straight down. It should cock. If it doesn't, open the bolt, push and hold the trigger forward (still pointing down) and close the bolt. It should stay cocked. If it does not, someone has honed the trigger and screwed up on the angle of the face of the sear or the notch in the trigger.
At this point, I am reluctant to try and instruct someone on how to fix it. If they are capable of doing the job, they will already know!
While it is usually no problem to get a Model 70 to 2 pounds or a little less, when they are set that light, you will not be able to drop the rifle butt first on the floor without it firing. This is no problem as long as you never load your rifle and drop it on the floor while looking into the muzzle! Regards, Bill

Bill,
Thanks for your help----I will give it another try!

A 2-3/4 lb trigger is target ready IMO, but then Im a hunter of big game and varmints, three pounds suits me well..

Yeah, but this is a heavy rifle with a very heavy barrel and a hugh stock!
By the time I lug it down to the firing line I might not have enough energy to pull a 3 # trigger!

Buy a jewel.......

To get your trigger that light normally requires some careful honing of the sear, your in the danger zone right now..I assume your talking a pre 64 Win..a super good trigger. and at 1.5 to 2 lbs its just too light on a rifle IMO and unnecessary, but Im not the gun cop, so get after it and I wish you the best.

competition shooters use a slap triger that goes off when the bolt closes..a strange set up to this old cowboy, but was educated by one of SAeeds buddy competition shooters on the advantage of bench rest triggers and they sure don't work on buffalo and plainsgame.

If you want a trigger below 1.5 lbs. your best off to get a bench rest one like a Jewel. The way to get a model 70 as light as possible is to put a lighter spring in it or thin the spring you have, Put the spring on a nail & run it up against a belt sander a little at a time. Keep checking as you go along.

Thanx Larry,
Before I try thinning the spring, I think I will go with Ernie the GS's lighter spring first.

Which vintage of M70 is this? Does the trigger have side to side play about its pivot pin?

Early 90's New Haven, Ct.

Will have to check out the side play!
