First of all, I've found that my Tikka's trigger is every bit as good as my Savage's Accu-Trigger once I adjusted it. It was as simple as inserting an allen key through the magazine well and giving it about 3/4's of a turn counterclockwise (and it is a "user-adjustable trigger, with the directions in the manual). The fit and finish of the Tikka is better than any Savage, and the composite stock is a far cry better then the Savage. Yes, the action is a fixed length with the bolt stop used to vary the bolt throw length. Mine is a .300 WSM, which means that almost all of the action length is used and I can cycle the bolt without breaking cheek weld.
I'll let the accuracy speak for itself. This is a load workup that I shot today. It was the first time I tried the "ladder method," so there is no one discrete group for each load. I labeled the shots on order they were fired. The "big" group has six shots in it.
