So, I happened to pick up a Yo Dave trigger spring for my Tikka T3 in .223. I had never heard of this product before and I must say, I am quite impressed with how easy it was to install and how much of an improvement you get with such a little spring. The end result: the weight of the trigger pull is half what it use to be and the pull is still smooth with a crisp break. Tikka owners, I highly recommend that you get in touch with Yo Dave and pick one up. For the price it is worth the try.
Below are some pics of the installation. I wanted to take it to the range to see if there were any improvements to group sizes but I kinda screwed that part up; I figured that while I had my gun in pieces, I may as well do a bedding job (yes I know this is adding a variable to the equation and thus my test to see if the trigger spring made any improvements is now un-scientific). When I took it to the range I started off shooting prone and things were looking OK (I zeroed on a target that is not pictured below) until I realized that there is a massive amount of mirage that comes off of snow, even at 100m (I was hoping to pass the .5MOA challange. FAIL). I then went to the bench and the groups opened waaaay up. The problem: I didn't tighten the action screws enough. While loading I figured the bedding job may play with the barrel harmonics so I loaded up 3 different loads. It looks like the old load is the one to try again: 24.4gr Varget, 80gr Berger VLDs, .004" off the lands, CCI BR4s, and neck sized Winchester brass.
Hopefully this inspires some of you to tinker then get out and shoot some more
