The only thing I did with the trigger is remove the adjustment screw and swap the spring for a lighter spring. Lighter spring / stock spring really did nothing. Both would only go down to 2.5lb before it would fail to be reliable and stay cocked.
I have another Tikka, and just to verify put the spring in there and I have that one at 1lb. So something's up with this trigger. I even swapped triggers around to my other Tikka rifle, and same behavior. Maybe it was off from the factory.
I made sure the spring / pin are pointed correctly, long way in. Reverified/swapped multiple times and double/triple checked.
Any other ideas? I'm calling Beretta on Monday, but I don't want to wait 3 weeks for turnaround, so I'm thinking I'll just get a Timney 2-stage for $200...
I do believe that you have put that steel pin in wrong way in, when you have put it back to your rifle.
There is no way that if you did also change that lighter spring, and you dd not gain nothing, there is something wrong, and nothing
else there can not be that you have done it wrong.
Dont say that you do not what you have been doing, but if you take that sping and pin out of the trigger too quick, you do not see
which way that pin is coming there, because those end are not the same kind, other is bigger than other.
