The Tikka and a Trijicon would be a great combo.
The only thing I would add is a suppressor........
this made me re-think my entire decision. But that is why I came here. I really wanted the .243 caliber. It has some sentimental attachment to me due to my hunting beginnings. However it doesn't look like the AB3 or the Tikka t3x Hunter come with a threaded barrel. I realize I can get any barrel threaded afterwards but I've never done this and the simplicity of having a rifle with an already threaded barrel seems obvious. I have never had a suppressor and love the idea of using one for hunting. At the moment we use electronic ear muffs.
It looks like the CZ American 600 would come in .243 with a wood stock and a threaded barrel. It also looks like a Howa 1500 does as well. Perhaps I need to get over the wooden stock thing and branch out.
I appreciate you all sharing your expertise.
