First, for liability reasons I have to tell you that only a qualified gunsmith should adjust a triger.
That being said a 70 trigger is rather easy to adjust.
1. Check and double check that your rifle is unloaded.
2. Remove three bolts holding action to stock and separate the two. You will now see the trigger assembly.
3. There is a threaded screw through the rear of the trigger with a jam nut at the trigger. This screw and nut adjust the trigger overtravel, be careful you can adjust this too tight and not be able to pull the trigger at all.
4. Further down the same screw is two more jam nuts and a spring. Loosen or tighten these nuts to adjust the trigger pull to your liking.
5. For extra peace of mind you may want to put some nail polish on the screw and nuts to keep them in place. DO NOT USE LOCTITE it may seize the tiny nuts permantly.
6. Reassemble the action to the stock and tighted the three screws. The front screw and the rear screw should be 65 INCH POUNDS and the middle screw should be just snug(over tightening the middle screw will cause the bolt to bind) I use a little loctite on this screw so it can be left looser.
7. Prior to using the rifle test the trigger weight. WARNING be sure the gun is unloaded and the safety off. Now butt down the rifle and be sure the trigger is not light enough to cause the rifle to fire.
A Winchester Model 70 is a rifle.
DO NOT ATTEMPT TO ADJUST THE TRIGGER PULL!!!!!!!!!!!!!!!!! Danger, Danger, Danger. It is no older than when the 300 WSM was introduced (2001)
Best left to a trained gunsmith
I do mnot understand your question?Are you asking if you have a winchester model 70,or how old,or if the rifle you have is a model 70.Please include the style of rifle(bolt action,lever action etc.)and the serial number,and model number.If these are posted in your question,then we can get you an answer.
There is many variables that will effect the price of a winchester model 70.First is it a pre-64 model 70 rifle,or is it a post 64 model 70 rifle?What kind of condition is the rifle in?Is the wood and metal in good condition or is it worn?The best way to answer your question is to know the serial number so that your rifle can be dated and have you describe in good detail the condition the rifle is in.
The Winchester model 70 is a bolt action sporting rifle. In 1936 Winchester introduced the bolt action rifle to the American Market. The model 70 was largely based on the Model 54.
Your two best options are to find a gunsmith and find a gunsmith. By the time you buy the necessary book(s) you could have paid a gunsmith to do it.
Is your Winchester Rifle a Model 70 or a Model 94? Bert H.
