Hey guys I’ve really enjoyed reading the forum, I just have a few questions. I want a very accurate .308 gun ½ moa @ 100 yrds Is it better to build a custom or buy stock (Sig Sauer SSG3000, Remington 40-XS, Sako TRG series, Tikka T3 in 308? I’ll only be using 150 to 152.5+/- grain bullets. What is the best barrel length and twist rate? Can a home builder install a custom barrel on an FN SPR action? I’d rather build myself as long as I don’t need a mill or a lathe. I don’t want to spend the money on the best (barrel or Action) I’ll settle for 2nd or 3rd best at least for now, What's the list for 1st, 2nd & 3rd for barrels & actions. I own other bolt guns but I’m looking for something more accurate something I could possibly shoot competitively here in Colorado. Thank you for you help. Happy Thanksgiving!
