My .308 is a Remingtom 700SA blueprinted. the bolt is sleeved,tactical bolt handle,holland over sized,excellerated firing pin.The barrel is a stainless unknown maker that I bought off of Ebay.That somebody started to cut a chamber in.It is now chambered in a .308 Palma match.It has a holland style muzzle break and it sits in a McMillan ANSCHUTZ molded in 50% OD green,25% grey & 25% black. Action and barrel are teflon coated 80% od green & 20% black and a Leupold 6-1/2-20 x40 mil dot sits on top.
I've never owned a Tikka but have several friends that own them and I don't think you could go wrong there.I have a hunch there will be more after market parts for the Tikka in the future.And you would do alright with a Remington too.I have 2 Rem. but they are pretty far from stock.But I guess I'm going to have to suggest you check out some Savage's as all of my personl future custom jobs will be using Savage actions.I guess it comes down to personal preference and they've all had their lemons.
take it for what it's worth.
p.s .308 is an awesome caliber.But I would suggest checking out .260 REM.
without God their is no hope for this country
