Lighten and Smooth the Weatherby Vanguard Trigger.

As always, when handling a firearm, the first step is to be certain that the firearm
is not loaded.
After removing the barreled action from the stock,
the next step is to locate the trigger housing mounting screw lock screw.
When the safety lever is in the
fire position, this screw is hidden under the bolt lock arm portion on the safety lever.
By moving the safety lever to the rear, or
"Safe" position, this locking screw will be exposed. Before attempting to remove the trigger housing screw,
back this locking screw out about 2 turns.

You can now remove the entire trigger assembly by
using a Phillips screwdriver to remove the trigger housing screw.

The green handled screwdriver
to an adjusting screw & locknut that should NOT be turned or adjusted in any way. This is the locknut and
screw located in the Rear of the trigger housing. If this screw is turned inward, the safety will not work.
If it is turned outward, you will have even more creep!
The"creep" in this trigger can be removed,
but it is not done by turning this screw, and this should be done by a gunsmith who is very familiar with this type of work,
as there is no room for error.
In this photo, the green
handled screwdriver has been placed on the weight of pull adjustment screw, which is at the Front of the trigger
Loosen this nut, and remove this screw. The spring
will not come out, because it is larger in diameter than the screw hole. The spring must come out from the rear, after
the trigger has been removed

After, removing the weight of pull adjusting screw and
its locknut, the next step is the removal of this E clip.

Now, you can easily push out the trigger pivot pin with a small
punch. The 2 pieces of metal in the picture are only there to support the trigger and the punch so they line up
for the photo.
After removing the pivot pin, (and the punch) you
will be able to pull the trigger straight down and out of the trigger housing. The trigger spring may also fall
out at this point, but if it does not, a few shakes of the trigger housing, and it will.

This 3/32 Punch provides a very easy means of guiding the new spring into its pocket
in the trigger housing. Just slide the spring on the punch, then start the tip of the punch into the housing as shown
in photo #8.
Continue to gently guide the punch with spring entirely through
the trigger housing as you see in photo #9. The tip of the punch is protruding through the hole that was opened up by
the removal of the weight of pull adjusting screw, described in step #5
Prepare the trigger for re-installation into the trigger
housing by placing a small dab of Loctite Moly Paste Lubricant on the upper end of the trigger where it and the sear
make contact with each other. I suggest that you make no effort at all to "stone" or "smooth" the
trigger or sear surfaces before applying this lubricant, as these surfaces are very nicely finished as they come from the
factory. Just let the Moly Paste do what it was born to do.

My new spring will
make your trigger pull light.
This Moly paste will make your trigger pull smooth.
That factory Vanguard scratchy feel will be gone.
Here are a few lines from Loctite's product
description sheet for Moly Paste. They say it contains 65% molybdenum disulfide for maximum lubricity.
Under typical applications, they say, no chatter or "stick-slip", they also say "stands
up under high static or slow-moving loads.
Loctite says that Moly Paste stands up under "slow moving loads" I think of the slow deliberate pull of a rifle
trigger. When Loctite uses the words "stick-Slip" I think of a Vanguard rifle trigger. MSC Industrial
Supply is one source for this product. Loctite part # 51048 for an 8 ounce brush top can and the cost is about
$30.00. I am told that Honda also sells a very similar product available in a 3 ounce tube, it is Honda Moly 60 paste,
# 08734-0001. Just Google either part number for lots of information.
OK, I will get off my Moly Paste soap box, and move on to the next step
which is removing the punch, while at the same time leaving the spring in place, just turn the trigger housing so that the
punch handle is pointing straight up, then gently pull the punch handle upward, and out of the spring, and the trigger

When re-installing the trigger into the trigger housing, it will
be necessary to slightly compress the end of the new trigger spring. This is to allow passage of the trigger as it is
being pushed upward to a point where the trigger pivot pin can be re-installed.
Hold this spring compressed
with a small punch or screw driver as seen in photo #11.

replacing the trigger pivot pin, snap this little E clip back into place.
replace the weight of pull adjustment screw and the lock
nut that you removed in photo #5.
Re-install the trigger assembly on the receiver with the Philips head screw, lock this screw in place by tightening
the trigger housing screw lock screw, as seen in photo #2.

With a "Varmint" spring installed in the trigger, and the trigger assembly
back on the receiver, we have a trigger pull weight of 2 lbs. 2.7 ounces. This weight will vary from gun to gun. Always check the trigger and safety for reliable function at this time.
Nothing has been done to adjust the creep at this point. This
part of a trigger job, should be left to a gunsmith who is very familiar with this type of work.
