So first off I know absolutely nothing about building a rifle or changing the caliber of a rifle. I have hunted my whole life but haven’t ever been down that rabbit whole! I’ve been watching that Tikka build thread and it’s kinda got me all fired up those are some sweet looking rifles. I would like to build a 280 ai. My questions are what caliber Tikka would be best to start with? What all is involved in it. How many different parts do I need and about how much money I’m I looking at? These are probably all newbie questions but starting to get sucked into the rabbit hole. Thanks for any info.
