Double Set Trigger adjustments
      #90355 - 02/12/07 04:55 PM

I have several guns with Single or Double set triggers. I love to use them, but I have one that is very, very light. I have never measured the pull set, but, I can barely feel my finger touch the trigger when it fires on the set trigger is set. I think this is way too light for hunting situations and may have cost me a Fine buck last year.
I have never tried to adjust the pressure / weight of pull on my set triggers. Can someone advise the best way to adjust the pull? The on I want to adjust is a double set with the typical screw between the triggers. Rear trigger is the set. I have tried to turn the screw (but not with much force) but it did not move. Is there a particular way? Should it be Set or at rest? In the Cocked state?
Please, I need to have some info if you can. This is Saturday December1 and I go on a hunt with the rifle in 6 days.
Thanks for any advise.

I bekieve a pull trigger can still be pulled normally without being preset by the rear set trigger.This should still fire the rifle. Whether it has an adverse effect on the double trigger mechanism I don't know.

If I am doing a no-no then someone please speak up.

Hopefully can adjust the trigger as you describe--

That little screw between the triggers adjusts set-trigger weight. Usually, it's sealed (varnish, loctite, etc.) when adjusted to prevent it from coming loose. Usually you may free the screw by applying heat from a soldering iron. When adjusted to proper weight, I'd advise to lock the screw with nail varnish, loctite, etc.
It is possible to fire the rifle in unset mode but then the trigger pull is generally horrible.

Hoppdoc and Andre are both correct.

I have a rifle with a similarly light trigger, and I have trained myself to use it. I pull the rear trigger, then put my finger on the front of the trigger guard until I am ready to break the shot. Then I bring the finger back, touch the front trigger, and break a good shot. It reminds me of "slapping" a shotgun trigger, only lighter.

The screw Andre points to is the set adjustment, and you can adjust the set trigger pull weight yourself. However, I've never examined one that had been adjusted by an amateur that I liked. Use caution.

Take care, Tom

I did some looking round the net and apparently I am not entirely correct--, apparently the trigger I would be referring to would be a Double phase, Double Set trigger. Other types exist.

The use of DST's is not for novices.Great for longer shots and wonderful training for breathing and rifle control.You had better be ready when touching the front trigger!!

Once the trigger has been set I feel somewhat compeled to shoot.

The procedure to "deset" a already set trigger is no fun-pull on the rear trigger while manipulating the front without firing the rifle--kinda hairy!! Had a buddy GD who shot his mauser with DST's while trying to "deset" it and also while leaving the front trigger SET and bumping it in his shooting house.He was "stressed" over his 3 ounce trigger.

Any pearls out there for desetting a set trigger without going to an empty chamber on the rifle?

Definitely not for novices and requiring a bit of attention and concentration.--

Adjusting a double set trigger is a simple task with no pitfalls.

The screw between the triggers is all you manipulate.

before doing anything MAKE DAMN SURE THE RIFLE IS UNLOADED.

As stated above, this screw must turn freely and should not be forced. If your's won't turn, try a little penetrating oil first. Don't use too much so as to allow the oil to contact any wood. Let it soak in while lightly tapping the adjustment screw. It should free up.

If that doesn't work, try a little heat from a soldering iron. Just apply the hot soldering iron to the head of the adjusting screw until it gets pretty warm. Then let everything cool off and try to turn the screw. Don't try to turn it while hot, as you have the screw hotter than the surrounding metal, which actually makes it tighter. Once it is cool it has contracted back to size and should turn. If it doesn't, try the penetrating oil again.

Once the screw will turn, you're almost home, and certainly at the fun part. Have no fear from this point on.

To adjust the screw, again MAKE DAMN SURE THE RIFLE IS UNLOADED. This can be done with the rifle uncocked or even with the bolt out of the rifle (assuming it is a bolt gun). Set the triggers. Then turn the screw clockwise (in) until the set trigger releases. In your case, this isn't going to take much. Pay attention to how much of a rotation it takes to release the trigger. Quit turning as soon as the set trigger releases.

Now back the adjustment screw out (counter-clockwise) about one full turn. This increases the engagement of the tiny sear between the set trigger and the firing trigger. Set the triggers and give it a try. If you like it, you're done. But you may feel some "creep" in the letoff of the set trigger, in which case you need to turn the adjustment screw a bit tighter (clockwise) to eliminate some of the engagement of the trigger sear. Keep trying and turning until you have exactly what you want. In my experience somewhere around 1/4 to 1/2 turn from letoff is good. This is something you can try till your heart's content. You are hurting nothing. Remember, your baseline is where the set releases, and you work back from that point.

I do not recommend putting loctite or sealer on the adjustment screw after adjustment. Generally this screw will not turn on its own. You want to be able to adjust this screw from time to time to suit your fancy.

That's all there is to it. Nothing fancy and no rocket science. Your biggest problem is getting the screw to turn without buggering the head of it.

A single set trigger adjusts the same way also. This is not a spring adjustment. Normally the spring cannot be adjusted at all. You are adjusting the sear engagement between the set (rear) trigger and the letoff (front) trigger.

Good luck,
Curl

Dear Cpt Curl:
thank you for the complete explaination. I will follow the process. I do know that on a cold morning, with cold fingers, the set is way too light. I have taken several game animals with the gun. Using the set trigger, but did totally miss an nice old eight point whitetail last year because it went off a bit premature. I didn't even feel the touch. The unset trigger pull of the forward trigger is very heavy and not very crisp. I will let you know how it goes.
Thanks again.

Mine are all hammer guns. I just pull the trigger and carefully lower the hammer. I know that's not much help, sorry.

Take care, Tom

The safest routine I have come up with is to use BOTH hands and while my right hand applies constant pressure to the rear trigger, very gently put pressure on the front trigger with the left forefinger and then release the back to "unset" the trigger.

Bad news is that you must remove your hand from the forend, loosing directional control and any screwup may cause the rifle to fire--
That is releasing the rear trigger too soon,or pulling back to hard on the front trigger or some other variant of the above.

Basically you have to be methodical and CAREFUL AS HELL, or the rifle may go off unexpectedly.My buddie GD is a believer!!

Hi,
Good info as usual!

88Mausporter,
I have never move set trigger regulation on my guns (I have two rifles with set trigger) so I have no experience but I found more info here:

Martin:
Thanks to our good friend on the other side of the Equator from us here in this western hemisphere. Have I told you that the other side of my family is over the Cordillera in Chile? Not as much of a hunting and shooting country as Argentina, but I don't know why.
I have been from the Border of Peru to Porto Mont and see so much oppotuntity for some good wing shooting or boar hunt, but little in the way of action.
Thanks for the Links. I am going to try CptCurl's suggestion. This particular rifle of mine is onf of my 88 Mauser sporters. My other set trigger guns are drillings and combinations.
Thanks,

To "uncock" a DST, simply put the action on "Safe", pull the rear trigger with your middle finger and touch the front trigger with the index finger, then ease the rear trigger forward. Takes some practice. A single set trigger can be unset the same way, by putting the rifle on "Safe" and simply touching the trigger off. In both cases, the muzzle should naturally be pointed in a safe direction.

A friend of mine was shooting his Krieghoff Teck .458 WM O/U double rifle in the usual sequence of front trigger first, rear trigger second, when he decided to reverse the sequence. Unfortunately, he forgot that he had already set the front trigger. He ended up with a nice half moon scar over his eyebrow and a bent scope tube when both barrels went off in rapid sequence. I would never have a set trigger on a rifle for dangerous game.

88MauSporter,
Yes I remember you like Mausers from down south. LOL
I do not remember seen pictures of your sporter M88, isnt it?

To "decock" my set triggers, I first open the action on my Sauer on the bolt of my Mauser and then, pointing in a safe direction, simply press the trigger.

Thanks
Martin

I have 2 rifles with DST's, both oldies.I like shooting them alot!!

What I would really enjoy is a DST on my Beanfield Remington Sendero 7mm Mag with its 4x16 Swarovski TDS but I don't want to mess with the gun and Remington would never have DST's on such a gun due to liability concerns--

Oh well--

I have a Sauer Drilling 16-16-8X57JR the front trigger is set by pushing it forward. Can I assume it is adjustable in the same way as the double set trigger?

With my Sauer drilling, turning the adjustment screw clockwise (in) decreases the pull weight and turning it counter-clockwise (out) increases it.

Thanks ALL! thanks CptCurl, as I used your instructions step by step. I now have a bit heavier pull that seems more comfortable.
I did go hunting big deer this last week. I must say I enjoyed it all. I hunted hard and saw the deer I was going to take. Three days of hunting, and didn't get a shot I was willing to take. Open sights, my eyes, bad predawn or after dusk sightings of the deer. With a good scope, he would have been mine. I lost the 20- 30 minutes of critical hunting time not having a scope. Leason learned.
As my 11 year old said, who did take a nice free-ranging black buck, "Dad, you didn't get dust!"
He hasn't let me live down last year's miss I mentioned earlier on this string. He was full witness after taking his deer at an honest 208 long paces.
Next year, my other '88 Mauser sporter with the claw bases will be mounted with a good scope and now a good trigger too. Both will go for different times of day when possible.
Best to all as we wrap this one up.
