The Tikka T3 trigger is pretty good for a $650 rifle, I'd say. But if you want a better one, you might try Jardinc.com The are the only place I found that sells an aftermarket trigger for a T3. I tried a Timney - they said it would fit, but it did not. Jard sells upgrade parts for the existing trigger group, or a full replacement for a few bucks more. They say the trigger pull can be set down to 14 oz. I haven't bought one, but have experienced the issues others have noted on the stock unit. Still, my 300wsm T3 with the stock trigger can fairly regularly shoot 1/2 moa 3-shot groups. (I have a couple 3/8" groups. The rifle is more precise than I am, I hate to admit). If I do buy one I'll re-post and tell how well I liked it. If someone else does first, how about letting the rest of us know?
Also, someone said the 300wsm recoil was not brutal. Compared to what? I bought a Limbsaver pad and found it to be a limb saver (ok that was stupid, but true). Call me a weenie, but the best money I spent was the OPS muzzle break from E. Aurthur Brown. I can shoot 50 HOT loads in an afternoon in a light shirt, and my shoulder doesn't turn black and blue - like it did with the stock gun after I first bought it and tried to put a box of shells through it. And, when I take it to the range now and touch off the first round, the guy next to me invariably says "what the hell have you got there?". Those muzzle breaks direct a lot of pressure back and to the side of you. No kidding. They FEEL the concussion. ha ha. I love that.
