I have a Sako TRG-S Firebird (7mm) and like it just fine. Maybe my chronograph technique is bad, but I've always gotten speeds on the factory loads that matched the box claim, and very good accuracy. Handloads (yes, they do sell brass) did even better, but case life is poor.
I've taken deer, elk, and a very long distance problem bear.
I keep thinking I'll rebarrel into .338 Lapua or have Kirby do some wildcat magic in 7mm Allen Mag, but this one keeps working.
Ok, that's the good news.
I also had, for a very brief while, a TRG-S in the Warbird, with a Christensen carbon fiber barrel. Factory loads were quite mediocre, and showed pressure signs. Handloads (at "starting load") also showed pressure signs. Rather than rebarrel it, I sold it.
I also held and shot one of the Lazzeroni custom rifles
. Nice, but too pricey for me.
