Trigger pull weight

I understand that the minimum trigger pull for 10m air pistol is 500 grams. Is there no correlating rule for 10m air rifle? In what weight range do most 10m air rifle shooters set their trigger?

No. No minimum trigger weight under ISSF rules.

Based on the context here I will assume you are shooting a precision air rifle.

Part of setting the trigger pull weight will depend on the experience of the shooter. Especially for a newer shooter it is easy to get the trigger too light and they can develop the tendency to jerk or slap the trigger rather than squeeze it.

With that warning, shooters with some experience who have measured it, often report a final trigger weight in the range of 100 to 200 grams. Assuming you can adjust the first stage it should be 1/2 to say 3/4 the weight of the second stage.

200gr is very hard for an air rifle trigger.

I believe should be around 80-150gr, with a very light first stage (about 1/4 of the trigger weight)

I shoot with 120g and it's the heaviest weight on my team.

My Anschutz 9003S2 has a factory trigger that ranges from 30-150 grams. I have mine set to about 100 grams. That is the lightest I can control. The trigger is so crisp it is hard to describe. I had two 9003s, and the new trigger is better than the 5018s. I have the 5018 triggers set to the same weight.

Most shooters at my club (with the average of 96+) have their trigger weight set between 70 & 90 gr.
If you have a good trigger pull technique with a good stability then a light trigger is better, you might notice some 9's turn into 10's just by doing that.
A heavy trigger needs slightly more time to pull, so unless you have an extremely steady position don't go with more than 90 gr, you also don't want a very light trigger either.
Try 90 gr for a start and see how it feels, you can then try a heavier or a lighter trigger. It all depends on how good your trigger control technique is.

Hope this helps,

I beg to differ, a heavier trigger takes no longer to pull than a light trigger. Even more so when we are talking about just grams.

What you are doing though is applying more energy into the system with a heavier trigger, which if poorly setup could be applied off centre and inducing a higher likelihood of pushing or pulling shots off target, but again a few grams is minimal.

Lots of discussion and opinions here:

I will go back to something that Simkovitch said, that 200 gr would be a very hard (stiff) trigger for air rifle. I will agree, for an experienced shooter 200 gr would be high. This is of course why these things are adjustable. Too light a trigger for an inexperienced shooter can easily lead to bad habits and poor trigger control techniques. (If your position isn't very steady then there is no observable penalty for jerking a light trigger.)

Some folks find that a slightly stiffer trigger helps them settle down when coming on to the target, others it just irritates them.

Some of this is all in what you get used to, think about the 300m Standard rifle, trigger must lift 1500 grams!!!

At the end of the day the absolute requirement is that the trigger be safe.

I know toplevel shooters with 25-35 grams. Probably only Feinwerkbau and Walther are able to be setup like this. Between 70 and 100 gram is the avarage.

Doesn't the 5018 only go down to 100 grams?
