Does adjusting trigger pull move your POI?

[tarponhead]

Wondering if I have to re-zero, if I drop the action out of the stock to adjust the trigger on a Tikka M695. I assume so, but is it the new trigger weight that would potentially change the PO,I or minute changes in the stock alignment? I would use a torque screw driver, but still, any views?

Done the same with a M690 with no change in POI. Obviously tried to tighten up to similar torque but only guessing. The bigger the difference in trigger weight the more likely your shots will end up in a slightly different place but that really depends on the quality of your trigger control/release.

I would say if the action has been out of the stock then at least check zero, changing the trigger weight won't change it only the way you shoot it.

I cant see it my self but a lack of confidence in your kit is no fun at all

Id stick one round in a target / mark on a tree what ever just to get my confidence back to 100%

Apart from the fact that you'll be removing the action from the stock and the potential for a change in poi associated with that procedure. I would want/need to get used to the new pull/break of the trigger with associated recoil and not just dry fire it.

I dont see why it would change POI. especially if the barrel is floating off the stock. the barrel/action/scope set up was not tampered with in any way. and it was screwed back correctly...
if the barrel is not floating however, as it isnt in some rifles, then taking the stock off and putting it back on in the slightest way different can cause a change in POI due to the barrel not touching in exactly the same spot as before and therefore not resonating in exactly the same way as before it was taken off. but this can all be avoided with good bedding. (which i am looking forward to doing sometime soon for this very reason.)

If I switch from normal trigger to set trigger, my POI shifts slightly high.

Very interesting. Once upon a time I had a Ruger MKII that had a 9lb pull out of the box. I'm sure my shooting improved when I got it lightened to ~3lbs. Regards JCS

A heavy trigger will = bad Grinch thus change a poi if you hav't had enough time to get used to it , A nice crisp trigger will help you avoid this, my 695 is set at 2.3/4 lb , I have no loss of poi . more trigger time and practice with what you have got will also help and bad finger control is another reason for poi shift . don't mean this before I get jumped on lol

 

[Dickie]

Totsy I think you need more practice with the set trigger never had any change when using the ones on my Styer or T3

On my experience, yes, you often get a small shift in POI. Bigger in an unbedded rifle, but often appreciable even in a bedded rifle.

But not usually enough to really worry about

I'ts only natural to shoot to a slightly different POA with a lighter pull very marginal though .I have a krico with a set trigger in 22Hornet on set trigger it is devastatingly accurate because you only have to think squeeze and the round is on its way.

There are two different questions here. 1) if you take the barrelled action out of the stock and replace should you check zero for a shift in POI and 2) if you change to a set/light trigger should you check zero for a change in POI.

1) Yes. This could be a physical change. Even in a well bedded rifle if the torque settings are different when you put it back into the stock the POI could change slightly - but it shouldn't be much. In a rifle that has not been bedded it could shift quite a bit, so definitely worth doing.

2) Possibly. If you are going from a heavy trigger to a set or very light trigger you are likely to change the POI. There can be a significant difference between squeezing a heavy trigger and wondering when it's going to break and putting the smallest pressure on a trigger and it going off almost subconsciously, the second usually being the more accurate method.

And why wouldn't you check it? Much better to be sure than to get into a deer and then start to doubt yourself or find that there is a problem. You need to get used to the new trigger pull anyway.

Will very much depend on your trigger technique and whether you pull directly back nice and smoothly and have good follow through or whether you rely on a light trigger so as to make up for poor technique.
