Consistant Trigger Pulls

My Model 70s trigger pull seems to range from 3 to something over 4 1/2 pounds. What is necessary to get the pull consistant?

And, yes, everything is clean and lubed. [Smile]

Thanks, Joe.

JMac,

I at onetime thought I knew my way around a model 70 trigger, and I do know how they are to be adjusted. However I have come to be of the opinion that in many cases it requires a rework of the surfaces, to obtain the best results. I have had two done in the last several years, one by Dave Gentry and Gene Simillion did the other, they are the best Mdl. 70 triggers I have ever pulled.

I have read and been told by smiths I tend to trust, that the timing/working of the safety can also play a part, but I have not had this done. I know that the safety rework is one of the many things D'Arcy Echols does to the Mdl. 70 action.

This is also true for the Remingtons, polishing and reducing surface to surface contact.

JMac,
This is a topic that could literally take hours to anwswer completely, but here's a couple pieces of the pie.
1)The trigger and sear contact points need to be stoned to remove burrs and minimize the amount of sear engagement on the trigger.
2) New hinge pins should be made and the reciever holes reamed oversize to accomodate a closer tolearance pin. Sometimes this is not necessary, but it is more often than not.
3) A new cocking piece should be made that will make consistent contact with the bolt shroud with a fit of no more than .001" slop.
4) A new bolt shroud should be made that will be accurately timed to the bolt, as well as the receiver, ensuring that the cockingpiece and sear meet at the exact point every time.
5) The recievers are normally out of tolerance at the location at which the bolt shroud rests, causing excessive rotational play. This is where the new shroud, custom made of course, would have to come into play to take up the gap.

There are literally dozens more things that must be modified and adhered to in order to properly adjust a M70 trigger. Fortunately, you can obtain somewhat desirable results, for the most part, without quite as lengthy a process. This is especially true if your finger isn't too sensitive, or you like heavy, inconsistent, creepy triggers. Then of course there's those days when the stars aligned just right, and you get lucky. It's happened to me a couple of times I'll admit, but I won't hold my breath for next time.
