Hi There and welcome along,
Oh how your brain is going to be doing cart wheels for the next couple of months, with this that and the other but dont worry you will get through it...... NOT!!!
Now the one thing that you will find on this site in many shapes and forms, it will be disguised in many different ways but one resounding word will all ways come out..... QUALITY!! buy the very best you can afford if it takes a little while to save for it, save! you will never go wrong with buying quality gear.
With that said I have a toy box not full but over 50% of my rifles are Tikkas and Sakos, I luv em! but if I was going to spend that kind of money on a Sako TRG-42, dude, build custom!!!
It anit as scary as it sounds if youve never gone down that track before, you will have more satisfaction with the final product, and if you strike up a good raport with your smith any niggly problems will be hopefully sorted and more sound advise given, than the guy that just sold you that rifle of the shelf.
Im not bagging Sakos Im just giving you the same advise I would give anyone else, and you will probably find I wont be the only one on here saying it either.
There are smiths that a forum members and they know their shit, any advise they have is worth moon beams.
Ask heaps of questions here you will get the right answer.
All the best with what ever you decide on, either way its a hell of a ride
