Also first time poster... long time reader* Definitely an excellent forum.
Regards to that TRG-S, it's an excellent action. And very accurate. Handloads always will bring out the "best" when you find the barrels sweet-spot. Mine (when it wore the factory barrel) shot 1moa or so with factory loads.. but easily under 1/2 minute with handloads.. Factory stock at that time, no bedding or anything. (NOW..) I've since shot that barrel out/gone to a Krieger, changed stocks/bedded, etc etc with handloads I'm seeing consistent 1/4 or less groups... it's almost amazing. My personal best (@200y, not 100) is an honest 1/4" ! I myself didn't think I could shoot that good, but have so repeatedly since I've had the upgrades done. Brass prep, seating-depth, bullet tension.. the whole bit plays it's part in doing that (but that match barrel with good gunsmithing is the icing) If you put your time in to learn what to load in that rifle, you will be rewarded. Far as cost goes to do these upgrades, I'm sure many will tell you it's more than the rifle is worth... cuz it costs a few bucks. Barrel runs in the $5/600 range, stock/bottom metal also $600-ish together, chambering fees, brake install, add rail (sako dovetails piss-poor) paint (stock) Cerakote metals (if you wish) ...it doesn't take long to add up and put a guy in the $2000+ range* In my opinion though, go for it.. I wouldn't trade mine for gold. Wish I had another one. However, others will say it ain't worth it.. your call in the end
Once done though, the rifle will impress* No question about it.
