Hammerli International 208

OK, I give up !
What is the screw forward of the trigger pivot with the witness marks ?
Looks like may hold the buffer but not sure ?
The exploded view is poor quality and is difficult to see clearly.

Isn't that the switch to change from 1000g to 1360g trigger weight?

I found a link in the archives for a 208 manual. Might be of interest to some.

That manual doesn't show the screw/switch in question.

That doesn't surprise me as I believe it was only fitted on early 208, and not on any 208S.

Several years ago I mentioned it at the Hammerli service centre and not everyone there understood what I was talking about.

I believe that the Hammerli International 208 (model before the 208S) actually has three versions depending on the serial number.
Exploded parts diagram only show one version.
One version has a stop screw up on the frame
One version has the stop screw down on the trigger with nut.
This version has the trigger stop screw with nut and the marked screw in question.
I also believe there is an American version with safety.

David Levene is right. This is the adjustment screw on early model 208s which changes the trigger weight from 1000g to 1360g, and vice versa....

One of the things I noticed is that the trigger was just over 3 lbs, around 3.25. Since I plan on using this for Bullseye and ISSF matches, I'd like to get it down to 2.2lbs. Looking at the instructions on Pilkguns I tried to adjust the screw in the trigger, but that seemed to have no real impact on trigger weight. I know they made several types of triggers for the 208, and I also see that mine has a screw on the left side of the frame above the trigger (see the screw w/red dot in pic). Does that have an impact on trigger weight, or is there something else I should be looking at? Any info would be great, thanks!

Answer

The side screw really is just a coarse adjustment for the trigger pull weight, which can be used as a quick change device if desired (and was the reason it was added). The "correct" position is with the red dot on the screw aligned with the dot on the frame. However, it also needs to be at the current number of turns to be at the right weight, and the screw on the trigger needs to be correct.

The best option might be to turn it one complete turn at a time (with red dots aligned at the end) until the trigger pull is in the desired range, and then use the screw on the trigger as the fine adjustment. It is hard to tell from the picture if the matching dot on the screw is there or gone. If gone, just use the groove on the screw as the guide or alignment mark.

When making changes, don't forget which direction you are turning it, and how many turns. That way, if you've gone in the wrong directly, you can at least return to where you are now. With a trigger pull at about 1500 grams+, it sounds like it either has been rotated the 1360 gram setting and then another turn (if the red dots are aligned .... 1360 grams is 3.0 lbs), or there is another problem with the trigger.

The high trigger pull may also be due to insufficient or improper lubrication, and not due to a problem with the adjuster.

OK, I have now had a good play with the screw.
It turns a small cam to bias the trigger weight.
With the red dots aligned it gives you the higher weight.
Dots opposite (180 deg rotation) gives the low weight.
My spring may be old but rotated to align I get 1290g, away 1030g.
